Maybe the best proxy metric is whether the customer returns the product. But the store will also be willing to eat more returns on a higher margin item if they make more profit at the end of the day.
replyI don't think I agree. If I overpay by 10%, I'll never know it and probably wouldn't return it even if I did know--once the shrinkwrap is off, too late. If a superior product exists but I don't find it, by definition I wouldn't know and wouldn't return the thing I did buy.
