I agree wholeheartedly. I think, like Amshak said, there are different levels of being a scalper. In some instances, price inflating may be justified. The following are my examples of when it's okay to inflate prices.
1) You overpaid to acquire the item. Now all you want to do is make back what you put into it. A good case in point here is the Fan Club, with their outrageous shipping prices, at least to Canada.
2) You own a store, and you have to charge a little more per figure to help cover your overhead. As long as you keep your prices the same across the board, and don't add, say, 30% to your shortpack in a case.
3) Trade bait. If you pick up an extra of something, knowing it's extremely rare, and you already have one, even though it's a borderline situation, I'd accept this under one condition. Someone may have done the same thing with a rare item you need, and using these rare items as trade material is fair, as long as you keep your values attached to it reasonable.
4) The rare item in question is no longer shipping in any current assortment. Once it stops being a regularly shipped item, then I think prices can go up little. Remember, though, it's only worth what someone will pay for it, so keep the prices concurrent with what it might sell on ebay for, and it would be nice if the price were a little lower than that.
Scalpers, at least the worst kind, are the idiots who hang around toy departments every day, learn when items are received and placed on the floor, and make contacts with employees in those departments. If you are hunting them down with the sole purpose if reselling them at skyhigh prices, and have no interest in keeping the items yourself, then you are the most vile of scalpers.
