While I don't necessarily disagree with you guys and what 3EB did in this case was kind of shitty, seing as how they could have easily done something cool and auctioned these off for charity, etc, given their level of visibility and assumed financial position having been around for so long and sold millions of records in the past, I have to play devil's advocate for a minute.
Why is it okay as a record collector to pay upwards of $200 for an LP from some random person on eBay, but it's not okay for a band to charge that amount of money for the same collector's item? If you're willing to pay that much in the first place, wouldn't you rather the money be going directly to support a band you like rather than some kid looking to make a quick buck? Especially if they're a struggling up-and-coming band who could actually use that money to stay on the road.
Not that I think bands should do that, but it's an interesting question. Seems like there's a double standard there and for some reason it seems like bands shouldn't be allowed to take advantage of market value for a product THEY created. I can't think of another business where that happens. No one shits on a painter for selling their work for hundreds of thousands of dollars at art shows. Or maybe they do, I don't know. I'm just thinking out loud.
I like your painter example. One photographer in particular, Peter Lik, increases the prices of his prints every 10% he sells, so that the last 1% available end up costing ten or twenty times the price of the first few purchased.
When it comes to records, nobody likes someone who flips a record, so a band is held to the same standard. The item gaining appreciation over time is a different story, but these are promo/retail copies that were accidentally not sold (or purposely, who knows) and not personal items that have become difficult to part with and extremely valuable, so it seems more like flipping than collecting at this point.
To put it simply: this is the same thing that record label pulled with YFW original vinyl, they sold them for 150 a piece on eBay as they "kept finding more"
I do think it is up to the costumer (or fan) to keep that in check by not purchasing products that they are being overcharged for and understand the band is just trying to make a quick buck.
