Some people noted this was a tactic to get around fees, but eBay changed their policy a while back. Final value fees now apply to shipping costs as well to thwart this practice. So eBay gets the same final value fee for a 30 dollar item with free shipping or a 1 dollar item with 29 dollar shipping. I think it is more likely they are trying to get out of returns or trick people into buying their item who don't have the item cost + shipping filter turned on
