No. I dont mind the word scalper. And, to address what I bolded, the reason I do not believe this would happen is everything bought is not being resold. Only a % of it. What % is anyone's guess. But I think it is fair to assume that it is well less than half. The economics of the price increase would discourge hoarding, making it impossible for resellers to profit off of those that do not. To your point, it certainly would continue to a point. But eventually, if the big box raise prices, the amount being bought for personal consumption would decline no matter what the scalpers did. Also, they have limited capital. If all of a sudden the price doubled many of the resellers could not continue to do what they are doing today. The high resellers disappear because there is product on the sales floors.
If it did happen, however, you are right. Eventually nobody buys anything. And you know what happens then? Deep discounts.
