it is not throwed away it is threw away DUHH! and you cant get it back no way you can....sorry if you still have birth certificates you can get a bear on it but not store credits :)
sorry i think you half to buy another one
the same thing happened to me and my sister!
You can still buy stuff
If you paid with a credit card, they might be able to print you up another copy of your receipt based on the information on the credit card billing statement.
Sorry, but I believe you are out of luck. Next time keep a close hold on the receipt. Since you don't have a local store you can purchase Build-A-Bear furry friends and accessories from their website and get additional codes that way. Good luck!

Do you still have the birth certificate because the code is on the birth certificate.
