You guys are the best! I first met Dan and he was great. Then I met Emily and Ashley and they treated me great! I will be telling everyone to come to T-Mobile at Costco! I won't be going back to the store in Enfield by stop and shop.

Emily and Dan were very nice and took really good care of me. I had a couple of issues with the billing but they were quickly dealt with and resolved. I traded my old iPhone 14 Plus for which I’m getting over $650 in bill credit over the next 24 months and I’m enjoying my new iPhone 17 pro.

Love Costco! This location is huge and surprisingly doesn't get as crowded as other Costco's. It is clean and they have a good amount of samples throughout the store. The parking lot is huge as well so plenty of parking. Good selection of produce and meat here too. Self checkout goes by fast.
