In fact, I'll pay for stars too. If you're not doing this deal, you can buy a starbucks card between $18 and $20 value, add $20 and I'll pay cost for the account. So you can make a couple cc points and whatever discount you got on the original GC. Will do this 5 times, pm if anyone interested.
Example: you buy an $18 gift card, register and add $20 to it, get the 300 stars, and pm me the card number and I'll quickpay you $38. Whole thing can take a few minutes.
