Hey cool, I am doing a starbucks auction too but mine is a little different. My deal: every 100 bids the gift card value goes up one dollar!.....So I am starting my bid at 100 ,meaning there is one dollar on the gift card...when it gets to 200 it will be two dollars, 500 will be five dollars, 1000 will be ten dollars and so on.Plus there is no limit....I know your doing one but thought you might be interested lol =)
