I just spotted yet another awesome soda coupon over at Coupons.com! GO HERE using zip 51501 under beverages to print a coupon for $1 Off ONE (1) Pepsi NEXT 12pk Regular, Vanilla Cherry or Mango Cola.
This coupon states available at Hy-vee but not redeem only at Hy-vee so you should be able to use it any store.
