Here is Kroger's Coupon Policy:
A few Quick Tips:
1. Kroger DOES double coupons up to $0.50 face value.
Example: You have a $0.25/1 coupon, they will double it to $0.50/1. If you have a $0.50/1 coupon, they will double it to $1.00/1.
2. Kroger only allows 3 of the same coupons for the same item per day.
3. Kroger DOES NOT give back overage. The coupon will be adjusted to purchase price if it exceeds the items value.
