I think that an individual, who is not a professional reseller, is dreaming about making huge profits selling a new bag. In fact, most resellers do not ask for or actually get "at least twice" the price of a bag IMHO. Ans asking price is one thing, selling price is another. And with those resellers who list at high prices, they have costs associated with selling (assuming they actually sell at that price). There may be those who make a large profit, but I bet they are not the norm. And I certainly cannot imagine a normal person making these huge profits they dream about. I certainly would not pay some inexperienced seller "at least twice" more than the purchase price.
