The comment I was responding to was implying that coupons were an outdated marketing strategy. I was saying that I think it can help companies achieve higher margins by selling at higher prices to wealthier customers, while still achieving sales at lower (but still profitable) prices with less wealthy customers.

I wasn't making any comment on the social good of price discrimination. I agree with you that some pricing strategies (buying in bulk, buying without loans/interest, rewards cards, etc) may tend to reward the wealthy. But that wasn't related to the point I was trying to make. I was trying to say that coupons seem like they could still be a useful marketing strategy for improving companies average margins per sale.
