Head over and print the $1/4 Chef Boyardee Canned or Microwavable Pasta coupon. Remember these are a participating item for the ConAgra $10 Publix gift card offer (when you buy $25 in participating products).
There is also a $1/3 RoseArt® products coupon available too. I am not sure if Publix carries this brand but the coupon should make for very inexpensive school supplies. I know the glue sticks and crayons are about a quarter each at Target. If Publix carries them, they will be very inexpensive as well!
Check under 30187 if you don't see the coupons.
