This is the worst Costco you could possibly go to. Ever. I bought a new S6 here awhile back, I paid for a brand new phone and got a $150 rebate, the guy working there told me about three times, "Wait 3 months to send in the rebate form, this is to make sure people don't get the rebate and return the phone." Seems reasonable, right? Well I waited 3 months and sent in the rebate and guess what! It was apparently too late! They said I had to send it in within 3 months and they just literally screwed me on purpose! Next I found out my phone wasn't even new!! It was refurbished! I only found out once the phone broke on its own and I had to contact the warranty dep. With my carrier.
Don't waste your time, money, and dignity even going near this shady, trashy Costco.
