> I strongly dislike such tactics since it causes people to waste a ton of time dealhunting, but isn't this usually to the benefit of the poor? These tactics allow companies to price discriminate and charge the rich more -- since they won't spend the time clipping coupons, waiting inline on black friday, or waiting for sales -- and thus theoretically subsidizes the 'discounted' prices for the poor.
Even without ericglyman's link to corroborating data, I would assume it goes the other way. Coupon-clipping and online deal-hunting requires time and, especially, emotional energy that the poor often don't have; and since the poor generally have to use essential items until they physically fail, and then scrabble frantically for the first available half-decent replacement, they don't have the luxury of waiting for special sales.
