Walmart complaint: Use of Mfg coupons

I understand that during these difficult and challenging times, not only for customers but retailers as well, Walmart needs to do better. I am disappointed that Walmart has stopped accepting mfg coupons. I have tried during several visits to try and use a coupon, that was not expired and matched the item exactly. The system won’t accept most of them. Once in awhile one will go thru. Walmart officials told me, new policy, if not in their system, they will not honor them. These are name brand, household coupons. If this is Walmart’s new progressive implementation to save money, I believe they picked a really bad time, in this economy, to do so. I do not believe a 50 cent coupon on cleaner, is worth losing customers, for not honoring it. I will happily take my business to other stores, whom seem to be happy to honor them. Prices have risen so fast at Walmart, that other realtors are comparable or even less expensive now them now. . You should be ashamed of your business practices, Walmart. I have told all my friends and they all agree, time to take our business to retail stores where they are happy to honor our coupons and give them the business instead.
