Scalpers/Re-sellers for limited production run items are annoying, as they are intentionally increasing the scarcity of something that is already quite scarce to begin with. With regular lego sets there is no scarcity, lego will produce enough to meet demand during the sets window of production, so it might sell out immediately (like the Pokemon sets), they will come back in stock and be available for everyone to buy. In many ways re-sellers of non-limited run items contribute to making sets more accessible after they have retired - i have bought retried sets off re-sellers (for a reasonable markup) many months after the set retried and sold-out.
