I posted this Schar coupon a few days ago but I wasn’t sure about the Schar products available at Walmart. I can confirm that the Schar wafers are available at most Walmarts and the coupon is still available so this means big overage!
Schar wafers start at $1.64 at Walmart

Final: FREE with $1.36 overage
