I was at Walmart today and they informed me that their coupon policy is once again changing. Apparently now all coupons must have bar codes on them to be valid. I thought all coupons did, but some don't (like the highliner ones). She accepted my coupons today but I'm sure they'll be cracking down soon.
Also a couple weeks ago I tried to use the printed $3.00 off Childrens tylenol from the Right at Home website and they would not accept it because all printed coupons must actually state "manufacturer's coupon" on it, and this one didn't. Is that an old policy or new?
Hope this helps!
