Good selection of quality items. Unique items sell out fast so if you see something new, better grab it.Consistently good selection of fruits, vegetables and meats. Left the other big name member box store years ago due to lack of selection, I have never looked back.

Looking for a product and Scott in electrical equipment was so helpful! He knew his products, and we took his suggestion and will be purchasing the best security system as soon as we can!

Great selections, no shortage of TP...yet. Masks are highly recommended here.Got our daughters Halloween costume there today #unicornprincess

Always have do many things I just cant be without. Kevin from Menomonee Falls store is awesome, always so friendly and helpful, he always reminds us to use our Costco charge. Last time he helped me load a # of cases of soda I couldnt lift. Love your store! 😊👍

Really good place here to shop, good deals on everything .

Its always clean and well stocked.

Store is clean and organized. Workers are almost annoyingly cheerful and helpful. Usually have essentials in stock. Cant really blame them if something is sold out. Food court is cheap, edible and fast.

Some good deals. Nothing Id go crazy for. Late July tortilla chips are delicious and enjoyed the pre-made stuffed peppers for an easy quick dinner.

Like browsing through Costco, however, Costco does Not have any Size 11 shoes, boots for women and they do Not have any Plus size clothing for women either.

We have items we regularly stock up on, and enjoy seeing whats new. Great prices and quality, in quantity.

I love that place! Its intoxicating and easy to buy way more than I need. Suffice it to say that I have enough popcorn to last my lifetime!

Went to the vision center. Picked out 2 pair of glasses. Very helpful employee. Glasses very reasonably priced

I love it there (you should try their pumpkin muffins)

Good selection, as of writing (10/19/21) they have a cheeses of the world selection

This is a very clean and well-organized store. Friendly cashiers are a bonus to the great prices.

Lots of things to shop for at reasonable prices. Love the gasoline prices- lowest price anywhere in Southeastern WI.

Love Costco, great food choices, excellent pizza by the slice, and how can you beat $1.50 hot dog/soda.

I went to load up on meat for awhile. Ended up buying a pack of 5 baby grand pianos. This place is GREAT!

This is what you will find checking out at 2pm on a Saturday at this Costco. There was no shopping carts either, so unless you have a lot of people to carry stuff just come on another day. Or rethink paying the yearly membership

Love this Costco!! Always clean and organized with the most friendly employees. I had to do some online returns and Matt in refunds was extremely professional and very nice and knowledgable.

Lots of great deals, and they believe in masking. Thank you for protecting your customers

I dont often post negative or positive but I am furious over the lack of service when my wife bought a new phone. The Way she was treated was ashame. They told her to go home and transfer the info herself.

Love being a Costco member! Big fan of buying in bulk and they almost ALWAYS have what I need. Especially love the liquor section. Kirkland vodka=yes please!

Love Costco! I go all the time. You never know when they have something new and at a great price.I buy my water, paper towels and TP every 2 wks besides other items.

I had the rudest service ever. My son and I have a black Costco card. I took my daughter and grandson shopping. I let her get a couple of things I couldnt afford. The minute the payment went through the girl at the self checkouts jumps at us. Accuses us of breaking the law by letting her use my card in front of my grandson and everyone up there. I said I would pay for all of it but she said it was to late. I have never been so humiliated in my life. Dont think I will shop there again.

I mean, its a Costco. If youve been to one, nothing much is going to change going to another one.One issue I had was that I could not find the Kirkland golf balls, and when I asked a worker where they were, they pointed in direction and kept walking without giving me specifics. When I did finally find the golf section, there were no Kirkland balls....

Great value for bulk purchases for anything you want, but not a everyday grocery store.

Honestly I could flash my library card and still get in if I wasnt a member...lolIts Costco. Not much else to say. They sell bulk of just about everything. We always get 2 hotdogs and 2 sodas if we want a quick lunch. Delicious and mega cheap.

Super clean an as super awesome. I wish I would win the lottery so I could just buy everything here!!

We practically live here at Costco. Its always clean and week stocked. Three people are always friendly.

They have the products that I need at a most economical cost.

Excellent prices, excellent return policies and excellent customer service.

Didnt know they dont take credit cards. Had to put items back. Before I did I asked for help lifting a safe from my cart to my car & they said no.

Its Costco. Inventory varies but their stuff is the best. Best prices on gas, food, and best of all, liquor!

Nice place to shop, always fund something extra to buy.

Love the early hours for seniors that I heard today they are stopping in July abt a month from now. Liked being able to shop and not have the crowds

I absolutely Love everything about this store.

Organized and clean. Found all we need, except sugar bags that are at this location are way way way too big.

Clean store. Quick checkout lines. Tables for dine-in are back.

Quick in and out. Rare but was a good experience

Love this place great prices always clean and super friendly thanks for the great experience

Nice, clean and friendly. When we filled our vehicle with our dogs, we were given treats for them!

This place never disappoints me. Friendly staff, huge selection and the prices are always very good.

Not much more can be said about Costo that already has not been said. For the quantity available for the prices charged Costco is my choice. Exceptional meats and bakery. Fruits, produce and liquids of all kinds. Much much more to peruse.

I received very poor and exceptionally rude service from the cashier on the very first day of getting Costco membership at this store. Basically, the cashier was angered by me not presenting their precious Costco membership card fast enough for him to scan. It was a very rude and impatient older gentleman there. A major turnoff at this point. I have noticed that in general many of their employees are quite rude. Costco is overhyped, based on my experiences there. Their gas station isnt even open past 7 pm on weekends, which is quite ridiculous, in my opinion. There is also a compulsive obsession of employees with masks. God forbid your mask is not fitting tight enough or your nose is not 100% covered, they will rush towards you to correct your behavior. Apparently, the fact that some customers are fully vaccinated makes absolutely no difference to staff with their obnoxious manners.

Friendly staff and customer service that is top notch. I will be going to back for sure. The parking is great. Getting in and out of the store and parking lot is very convenient. I look forward to seeing what deals that have on various products. They practice social distancing and managed everything very professionally.

Great store to shop, but not enough cashiers available for the crowds of people trying to check out during holiday shopping time. Otherwise wouldve given 5 stars.I got some great deals today & Im pleased with my purchases. They even had Pummelos today.. which is a fruit similar to a grapefruit, but much larger and less bitter.. delicious and hard to find anywhere else so I had to have them.And dont forget to buy the $4.99 whole rotisserie chickens.. they taste very delicious and are big, so you get your moneys worth with those.Stop by and check it out.

Nice products but dont have Signs to show you what products is in each aisle

Really liked shopping there.

Self check out is fantastic. Store was clean.

The people are always nice and willing to help out. The building is clean and the food is good.

Costco is a very good wholesale company. Great products, terrific customer service and happy employees. Have shopped here for many years.

Always pleased with the cleanliness and staff friendliness of this store. Now even better with self-checkout!

Costco across the country and Hawaii as always proved to be a great place to shop.

Not happy this time around, 25 people in each of the 3 lanes open and it was 4 pm on a Thursday. Took 40 min to get through check out.

1st time there.Loved it.

It was better when only 2 people were allowed in per membership. Why? No unsupervised children running wild.The store is clean, neat, and well stocked. Weve pretty much switched to buying all our meat here. Cheaper and I can prep it for freezer to make quick weeknight dinners. We also found that we like the quality of the steaks better than Sendiks. I like the produce, but plan that carefully as sometimes we cant use it all up with only two of us. (Which we knew going in. I was proud that we got through almost an entire 16oz container of salad greens before they went bad.) Can definitely see buying some mushrooms in bulk for a holiday party in the future.

Great Place, Christy was very helpful with our purchases, and we always enjoy seeing her when we come back.

Found items we needed that we were unable to find anywhere else. Employees were helpful and kind. Checkout was quick and efficient. Sales were amazing!

Good deals. Pleasant helpful staff.

Great one stop shopping, tire services, highly rated dog food at awesome price, convenient optical Dept, free food samples. Poor onion and bread flour selection; high butter prices. 4.5 stars

Purchased a TV today with my executive rebate. It was one of those days where I actually had it in my pocket but while reaching in my pocket it fell out. JOSH the gentleman working in the TV section found it and was asking members is this yours and it was mine.. .YIKES $200 I almost threw away but they care! Thanks to JOSH and the TV is sweet!

Visited with the intention of purchasing a $900 camera system, ring doorbell, and bacon. Approximately $1100 worth of goods. Walked around for about 15 minutes looking at and reading information on camera systems. Not one person asked if I needed assistance. However 2 emoyees made sure I was wearing my mask correctly. I decided to buy my bacon and leave and I was told I was up for renewal. I did not renew and I will never hold my breath that anyone will care. It is unfortunate when a company becomes so large your customer experience no longer matters. But at least everyone is wearing their mask properly.

For years I was a member of the other wholesale club. I mistakenly thought they were all alike. Boy was I wrong! Not only are the staff friendly and helpful, but EVERY DAY (before COVID) they have at least 10 samples of something out to let you try it before you buy it. And when you buy it, you have a full 90 days to see if you like it! Who does that? If you don’t like it, they have no hassle returns. Did I mention they also have a credit card that offers you a percentage back on your purchases? And that credit card also provides you with an additional warranty on your purchases. C’mon, why would you shop anywhere else?

Busy store as it always is. Best to go here not on the busy days.

Love Costco!! Everything I need is right there.

Very clean, and workers were extremely helpful

Every time I go to the Grafton Costco, all the employees are very helpful and polite

Now my favorite wholesale club.

It’s fine, and it’s huge, and has lots of unnecessary things that I somehow need in my life. It’s often way too crowded and there never seems to be enough checkouts open for speed of exiting... but I mean, it is what it is.

I allways get want I want there.

Great place for gluten free and organic vegetables and fruit.

Staff will bring out a electric cart to me when they see me. I really appreciate this. Clean store, if there are lines at checkout, they move along quickly.

Quick and thorough! Answered all questions.

Great service and selection.

Maybe the idea of this store just isn’t for me - easy to buy more than you need. But the real reason for 3 stars is the slow service at the checkout. Employees uncooperative and seemingly confused.

If you blindfolded me and put me in this place I can tell the difference between a Sams Club and this place. Same Same everything right down to my 10 minute wait in line.

Man oh man does warehouse really fit here. It was big and had everything if you are looking for non-specific things. It was my first time and I was wowed then I kinda went to meh.Perfect place for a family of 4+. The selection is exactly what you would expect. They had Kirkland brand versions of stuff but i saw most big brand names there as well.Most clothing available would fit most. I am a BIG dude(fat), i couldnt find any 3xl+ shirts, any pants above 42 waste, or any shoes above mens 12. Tbh I wasnt expecting too, but I wouldve be pleasantly surprised and would have boosted this review to 5 stars. Staff was friendly, the snacky bar had affordable hot dog meals.So all in all good trip!

Not a fan of the members system but they have everything. Weekend samples are the best.

The only place I buy gasoline anymore.

Pretty good deals, sometimes products rotate and they dont have them or something because i cannot find them sometimes, other than that no reason to give bad review.

This particular location is okay. Costco is usually pretty good. Sams club does appear to have more selections.

Great club store with everything you need and more.

Place has everything. Make sure that if you see something you like, you get it right away. It might not be there next time!

Always have what we need. Clean, organized, friendly, high quality products. Always impressed. It’s our main stop for shopping

Great place to stock up. Large selection of products.

Fast courteous check out! Just tried this salad. Its very good!

You are the best 👌

Its Costco, who doesnt love it?

Good place for all things. The thing I dont like at costco is they dont item address to their aisle. Its really hard to get which you want in this big store unless you got some power energy to walk around.

Great prices and very helped staff

My fiancée and I have been shopping here for the past couple months. We love the seemingly limitless options for food, clothing, alcohol, etc. If you want to be able to buy in bulk and be stocked up for a long time, this is the place to go!

I spend way too much time here! But I also save a lot of money!

Not better than Sams club...

Always great products in stock.

I love Costco! Great variety and fun employees. Theres a shopper dude that plays polka music. What a funny man!

Always a positive experience. Count myself lucky to walk away without spending $100. Today was not that day!

Great place if you have a growing family and need to stock up on supplies

Just shy of the hundred dollar club. Found more goodies then I had planned on. LOL

Was with a Friend, but Enjoyed the experience
