This is an excellent point. Another one in a similar vein is things like appliances or other big ticket purchases. The wealthy (or even middle class really, assuming any are left) is that they can buy a new washing machine for example when they're on sale. The poor essentially need to keep using the same washing machine until it dies, at which point either they need to go to the laundromat or buy a new one, and they have to get whatever one Home Depot has at the time at whatever price they're marked at.
