I'm not sure why its an issue to buy cheap and resell at a higher price, isnt that pretty much what every shop or trader in the world does? some items have a massive mark up on em so i guess it puts a few noses out of joint when you find out, but cars are some of the worst offenders, no one really thinks it costs 3 times as much to make a big merc as it does to make a ford focus but people still buy em.
