Note: Since the coupon doesn’t say “Redeem Only At Walmart” it can be used at other places too (It’s a suggestion, not a restriction)
Click here to visit the Coupons site and you’ll be able to print a coupon good for $1 off any Post Grape Nuts or Shredded Wheat cereal. (If needed use the zip code 55555 and click the “Food” category to find it faster)
If your Walgreens carries the smaller Shredded Wheat Original boxes (9.25 oz), then they should be priced at $1, which would be free after coupon.
