...buying multiples isn't the same as scalping. Scalping is, IMO, when you buy a toy and then sell it off at a jacked up price to make a profit, and especially when you buy out the whole shop thus forcing people to buy from you.

I'm not saying that I agree with people buying multiples straight off the bat as it can make toys harder for others to find. I personally think if that if someone wants a multiple then a better way would be to buy one first, then come back to that store in a week or so and if there are still toys left then grab another one. That way you've allowed time for other collectors (and kids) to get the toy if they want to. But unless you're going to sell the toy on at a higher price then I don't see how it's scalping.

Fun Fact: the black plague was deliberately transmitted to Europe after it was bio-weaponised by the Mongols in... 1357?
