I resell Lego sets and don't care if anyone else does it or not. What gets to be the problem is the stores themselves. Locally, TRU and the Lego store have limits on some sets that are in limited quantity. I have absolutely no problem with that and actually support it. I bought a few Prince of Persia sets, but only 2 of each to get the TRU bogo discount. So if there were 2 of a set left on the shelf, I put them in my cart without a second thought. I have no idea who bought the dozens or hundreds before me and this was towards the end of the 3-4 day sale.
I didn't buy any of the chromes and I don't really mind. But for one person to buy 100 is a little "eh?" First, TRU was stupid for allowing it. Second, if you can, then fine, but don't brag about it. Third, if a store only received 100 and I was able to get the case, I wouldn't take all.
As far as hoarding goes, there's a big difference between one guy going to multiple Targets as soon as the store opens and depleting their inventory of specific sets, which to me = Hoarding as opposed to someone else who has say, 50 of a certain set bought throughout the set run. There's quite a few sets that I have a good stock of, BUT, almost all are bought online and on sale. You could buy Echo Bases or Separatist Shuttles from Amazon at a 25-30% discount but only 3, which gave everyone a fair shot at them.
Also, and I don't know how, but there's been sets that people sold on Ebay for close to half MSRP. So buyers/collectors could even get better prices than those who stocked up.
I just don't see a difference between person A buying 20 sets at TRU to resell in the future vs person B who buys the same sets at the same place for the purpose of adding to his collection(Diorama or troll army, as examples). The same quantity gets depleted from the store shelf which affects the crying kid equally. Either both are hoarders or neither are.
As regards resellers, they do the exact same thing that Targets and TRU's do - they resell product, just at different times.
