It would seem that the term is very objective then isn't it?

How would I class a scalper? I guess it would be someone who buys the stock off the shelf and then sells it for higher retail than what they bought it for. If they were a speculator, then the length of time would negate any Scalper tendencies I guess.

In example of the Toys R Us Sale of space starscream, I would say that buying 3 or 4 of them, waiting for the sale to end and then selling them at even normal toys r us proces would be classed as scalping, as they have made an effort to keep the toys and profit from them. Lets say that the price is a great price $29.99 for example and the stock sells out at all TRU. Then someone who genuinely wants the toy is going to miss out due to another person being opportunistic.

It all comes down to intentions in the end.
