Here is a Buy One Get One Get One Free coupon that can be used on Chicken of the Sea Salmon. These are part of the Kroger Mega Sale for $0.79 so you will only pay $0.40 per pouch.
If you haven't done so, download and use your $2/2 Chicken of the Sea 2.5 oz Salmon pouches Kroger Digital Coupon. With this coupon you will actually make about $0.42 (because it takes the $2.00 from the pre-mega price).
I did test to make sure the $2/2 coupon would come off..and it did!
