There is a Stonyfield coupon available to print to save $2 off 3 yogurts. The YoBaby yogurt singles are about $.94 at Walmart. So $.27 each if you buy 3 and use the coupon. The 4 pks are $2.29 at Target making them $1.62 after coupon.
I also wanted to mention that you can get a $.75 off Earthbound Farms coupon.
