well, i am bothered with it because when people actually buy extra sets, only to sell them later, they will make the whole bunch sell out earlier.
if the demand for these items is that big, and there is very few offers (on ebay), market theory will dictate indeed: price will go up, and they will sell them for much more.
so by that rationale, the end might as well throw the price up themselves: as the ltd. editions are selling out, increase the price.
and then see how quickly they'd get flamed everywhere for being greedy bastards.
the people who sell them on ebay this quick after a release take an advantage of the end's disability to raise the price as the demand/offering increases.
if you sell a collectability years after it was released, it's different, because:
-you didn't buy it just with the intent to sell it and make a buck out of it
-the price went up over a course of years, you are not taking disadvantage over the original seller
also remember the Pale Folklore boxsets people bought on ebay, only a few days after the Day Of The Equinox festival. Agalloch could easily have asked more $ for it, plenty of people would have paid the money for it, but they too think it's ridiculous to sell a record for that much. instead they ask a more fair price, and then it's not fans who buy it, but businessmen. where is the fairness in that?
now, i can't really feel sorry for the idiot who bought that set on ebay, he should just have looked on the end website. but take all the people who would have loved getting their hands on one of the PF boxsets on the day of the equinox but couldnt have come there (from europe? yeah right!), and then have to pay 200 dollars for it on ebay? as a band, would you think that's fair trade?
still of course i understand you were so happy to sell all of those so quickly, that you have so many fans, it must be a risk every time you do something like this
