Kroger has Cottonelle toilet paper on sale for .99 this week. If you have the .50/1 coupons that were in the paper recently, and your store doubles, your toilet paper will be free! Check your store’s policies on doubling. In my area, you can only double three like coupons per transaction (if I am buying several, I will go late at night and do a few transactions back to back).
I have also heard that the Cottonelle toilet paper is a part of the buy 15 items, get an instant $3 rebate, but I can’t confirm this because I haven’t been to the actual store yet.
