**Update 9/1/11** Amy's has changed the program a bit. You now get to pick what item you want in exchange for your UPCs. http://www.amys.com/community/proof-of-purchase
I just got word from Katie @Amy's Kitchen that there is a reason to save the Proofs of Purchase from Amy's products! If you collect 25 Amy's Proofs of Purchase, you can mail them in and Amy's will send you a goodie bag with Amy's stuff and coupons!!!
Send your 25 Proofs of Purchase to-
Amy's Kitchen, Inc.
PO Box 4759
Petaluma, Ca 94955-4759
Thank you to Katie and Amy's Kitchen for allowing me to sleep at night again.
**Update 1/24/11** I got my gift box! Look here.
