K-MART is doubling a manufacturers coupon (value up to .99) this week July 24 - 30.
For example, a .75 cent coupon is doubled to $1.50.
They are not taking BOGO's but I have heard that they are permitting them for pet foods.
I don't normally shop at K-Mart, you may want to check with your local store to be sure that they are honoring the double coupons!
Here are a list of coupons under the .99 cent threshold.
