Anyone else done the T-Mobile switch through Costco?

I have basically had it with VZ’s expensive rates and shitty customer service. We’re planning on switching to T-Mobile this weekend via Costco because they have what looks like a pretty decent deal going on.

If you’ve one the $400 back deal, can you please tell me whether the $250 prepaid card was restricted to use only with T-Mobile or Costco? Reading the fine print on the Costco website makes it appear that that’s the case…in which case it’s still an okay deal but not a spectacular one.

If the $250 prepaid cards are limited to just Costco and T-Mobile’s site, we’ll probably still take it, as Christmas is coming up.

TY!
