So, why then, do manufacturers go through the trouble of putting DND or DNT on a coupon?
Great comment, thanks. This post is a few years old, but things are pretty much the same. I do not think that a manufacturer would try to stop a particular store from carrying a particular item at a steep discount. The stores change their sales too often for this to really be effective. Plus the only way to prevent it entirely would be to discontinue selling that product to that store, and that of course conflicts with the overall goal of selling more products to consumers. As I said before, I think the manufacturers are just being extra cautious and covering their bases to make sure they are not held liable for a doubled or tripled coupon value. It’s generally accepted that they are not, but this just makes certain.
