There is currently a coupon for $3.00/5 cans of Mighty Dog. I ordered a bunch of these coupons from ebay and I have used them at Dollar General, Walmart, and Kroger and they were all free after coupon. In the picture above I got 250 cans for free last weekend. Today, I got another 50 cans free at Kroger. I will end up with about 500 cans free by the time I use all my coupons!
The coupon will beep at Kroger and Dollar General and they will have to manually enter it.
