I found links from couponcravings to try stuff for free (basically they'll send a full rebate after you mail in receipts and UPC code).
These 2 I'm trying:
Kelloggs Cereal!! (Smart Start Strawberry Oat Bites or Frosted Mini Wheats Blueberry muffin, which sound absolutely tasty) The rebate form is here.
Great deal: Buy 1 (and get 1 free) at CVS this week, use 2 coupons from here (that'll take $2 off) and get a full refund of 1 box from the rebate. Is that sweet or what? I hope it'll work! It should.
BUN-dinos. No idea what they are or where I can find them. But if I do, at my grocery store, I'll love to try! Rebate form here. (This gotta be bfore 30 Aug, so hurry!)
