What stores honor expired or competitors coupons?

Most stores do not accept expired coupons as per their policy, however some stores will accept coupons slighlty past expiration date. There are two reasons for this, first of all, most manufacurer coupons will still scan for a few days and even up to a week or two past expiration before "beeping" so a lot of stores will not even notice. Secondly, most stores will turn in their coupons weekly so if a coupon expired on a Tuesday and they dont turn in coupons until the following Monday then they may still accept it through Monday. Each store is going to be different, so the best thing to do is just ask when you shop.

As far as competitor coupons, the stores that I know of are Harris Teeter and Publix. I don't know of any others.

I use www.afullcup.com to look at my favorite stores ads early and I use their shopping list feature to put my list togeather, pull my coupons and shop. It makes it so easy. Plus there is a great forum, blog and coupon database avaiable all in one place!
