check your Safeway store and see if they have PediaSure NutriPals bars usually found in the baby section and if they are on sale 2 for $4.00 use the $2.00 off coupons that were in one of the newspaper coupon inserts. The coupon expires 3/31/09 and shows a picture of the PediaSure 6 pack liquid.
The coupon can be used the the 6-pack boxes of NutriPals bars. Since they are 2 for $4.00 ($2.00 each) and the coupon is $2.00 off that makes these free. I got 7 boxes the other day with no problems.
