Bye Bye Extra Care Bucks

My husband was looking at the CVS ad this morning and he saw where they had Guitar Hero for the Wii for $39.99. He has wanted this game since we got the Wii last November. So I decided to surprise him with it. I had a $4/$20 and $36.79 in Extra Care Bucks. It cost me $4.10 (I also got a 20 oz soda). But he was so excited and it felt good to do something nice for him. But now I have no Extra Care Bucks left and have to start from scratch.
