About Costco Wholesale
Members-only warehouse selling a huge variety of items including bulk groceries, electronics & more.
Located at 3600 E Main St, Waterbury, CT 06705, Costco Wholesale operates as a warehouse store serving Waterbury in Connecticut. This page gathers the practical details people usually look for before visiting: where it is, how to reach it, when it opens and how customers rate it. Besides its main category, the business also describes itself as department store, so it may cover more than the name suggests.
This group covers shelters, breeders and the other places pet owners use: animal shelters and rescues place dogs and cats for adoption and often run low-cost vaccine and spay clinics; breeders raise puppies and kittens of particular breeds; pet cremation services and cemeteries help when a pet dies; pet photographers take portraits, often right after a fresh groom; and pet-friendly hotels and places welcome dogs. It also holds businesses that turned up next to groomers on the map but do not fit a pet category.
The business lists hours on 7 days of the week. On most of those days it is open 10 am–8:30 pm. As with most places, expect changes around holidays; the phone number below is the fastest way to confirm. The listed phone number is (203) 596-9967. Many businesses also reply to text messages on the same number if it is a cell phone. More information is available on its website, costco.com.
Customers rate it 4.6 out of 5 on Google across 3,607 reviews, placing it among the better-regarded warehouse store in Waterbury.
Waterbury is in Connecticut, in the Northeast, where four distinct seasons shape local life: hot humid summers, snowy winters that can close businesses for a day, and a dense pattern of towns where walking, transit and street parking all matter. Getting around Waterbury is easiest by car; street parking is metered in busy downtown areas, and most suburban businesses have their own lot. Ride-share apps such as Uber and Lyft operate across Connecticut's larger cities, and public transit varies from extensive to minimal.

This is where I get my eyeglasses - great staff and the best prices for lenses and frames! The whole store can be a busy place, but staff is working hard to ensure a positive experience for their customers. A quarter pound hot dog and a soda with a refill is only $1.50 - with a price like that, you can't afford to eat at home! And I love hearing parents yelling at their kids in such a wide variety of languages - God bless America!

I would like to recognize Teresa in the Service Department at Costco. She is always smiling, friendly, and very helpful. Every time I need assistance, she goes above and beyond to make sure I am taken care of. Her positive attitude and excellent customer service make every visit a pleasant experience. Costco is lucky to have such a wonderful employee. Thank you, Teresa, for your kindness and dedication! Also Manager Angelina and Mary Ann leads with professionalism and kindness, creating a welcoming environment for everyone.

Thank you, Teresa, Angelina, and Mary Ann, for all that you do!

Omg, never tried duck before... if you haven't, it's a very easy entry price, I think it was $22... try it sometime, Costco is the place to expand your menu.

I ordered food from the kiosk with a baby in my shopping cart. The woman at the exit would not let me take the cart to counter, leaving me no way pick my food up without leaving my baby unattended far away or somehow carrying both my baby and the food. She didn't offer me any solutions aside from explaining "it's policy." So I did not pick up the food that I had already paid for. I would hope Costco would have more family friendly policies. I'll be going to the Milford location now where I don't have this problem.

The Costco Liquor Store is a hidden gem! It has some of the lowest prices you’ll find anywhere on wine, beer, and spirits—and the best part? You don’t need a membership to shop there! The selection is impressive, with both name brands and Costco’s highly-rated Kirkland label. Whether you’re stocking up for a party or just grabbing a bottle or two, it’s 100% worth the stop. Great deals, great quality, and super convenient!
