...or simply trying to prevent others from getting a set in order to profit later on.
I disagree (to date, I haven't sold a gorram thing, and I haven't bought 90, or even 20 or 10 of anything), but if I were buying 90 Chrome Stormtroopers, I wouldn't be doing it to prevent others from getting them, I'd be doing it because I know, in the future, they will probably be worth something.
Again, it comes down to the stupidity of making these special sets that gets people at each others throats instead of just making products generally available to everybody. The way you look at it, no matter how FEW I buy, I'm still "preventing" someone else from buying it.
If LEGO is going to treat products like Beanie Babies, people are going to treat them that way.
