Head on over to their facebook page and "like" them to get their 1.00 coupon. If you are a Walmart shopper, use this coupon and that would make them .42 a piece. I know my kids have been asking for these, so I guess I can get them now :)
Walmart: Regular price .67
-1.00 on YoCrunch Yogurt Facebook Fan Page
Total: .42 when you buy four!
