I've been looking at some of the things people sell on AlphaBay and others, and there are huge disparities between the prices. I can find one person selling mdma for about 40 bucks a gram, and another person selling 10 grams for 90 bucks. I don't understand how there is that much of a difference. I am seeing this with almost everything. If anyone has any advice on how to approach some of these things it would be greatly appreciated
