Here's what I think about "greedy" people: you want something, and they have what you want. There's nothing stopping them from pricing whatever they want, especially when they know there will be dozens of people at their doorsteps with that kind of money in their hands.

The best way to get back at them, is to not buy their stuff and make your own! Then you can laugh at their 4m wands when you got it for, well, less than 4m.
