Sprinkles Cupcakes are some of the best in the area - judged by many (and I'd have to agree they're yummy).
SocialBuy is offering $10 worth of Sprinkles Cupcakes for $5 - you can purchase them the next two days. The voucher has to be used in full at one visit, but it's good until 1/31/2011.
Sprinkles is at Stanford Shopping Center. To get the deal, click here.
