Wow - I did not know that. Puts it in a different perspective for me. I am a professional artist and I have had my work re-sold by a gallery that bought it at a discount for more than double the retail in the past. Bad business.
I also found a copy of the Bioshock Artbook on ebay as well - the seller wants $1000 for it.
There is profit, and then there is greed. I won't even post the link to it because I think that the price is unfair. And if the seller is on the forum, sorry, but that's greedy dude.
