It's kind of late for them to be trying to push people to list things "auction style" when they've let the entire site be overrun with overpriced BIN items. It was bad enough when the ebay stores were filled with them, but now that they have that "list until sold" option they are apparently going to be cluttering up the auction listings until the end of time. All that is going to do it make people filter out BIN items when doing searches which will make it impossible for the people that actually try to list BIN items with reasonable prices to sell anything because no one will see the listings.
