Yall be careful with Starbucks. They closed all my cards, I had a card with $100 legit balance and they closed it. They even closed the cards with zero balance. This is mess up.
Did you "merge" the sellers cards into your "legit" card? NEVER do that. They will close any card that has any (cough)cheap(cough) cards attached to that they find suspect and you also lose you "real" funds. They can easily follow the transfer of cards and per their terms of service regarding gift cards you are SOL. That's the chance you take by buying this stuff. Win some, lose some.
