The Choos at least will easily sell for that on other sites, so no reason to go lower.
I haven't had luck selling them for that price on eBay or other sites.
I think that for $250+, most people would rather go to a department store and get the full experience, the option to return, guaranteed authenticity, etc... I also think that even though these items have MSRPs in the high hundreds, very few people actually pay that amount. And having a fancy label on the shoe does not make it desirable if the thing is hideous. I've seen some items on this thread that I'm frankly shocked made it out of the factory, let alone from a fancy designed.
