dagold99 i dont think the price of devices being sold on craigs list is going to be affected by HTC. There are so many other opportunities to get money for a device that HTC probably isnt on many peoples radar.. Sprint offers buy back, Best buy takes trade ins as well. Not to mention all the websites who offer to buy old phones.
Supply and demand will set the price for the equipment, not HTC low balling their own product on their website for buyback.
True HTC fans will pay more then others. Especially when some devices are carrier dependent, thinking EVO LTE. If someone really wants one on craigs list they will pay for it.
