I use this strategy as well, and have argued with many a wholesaler over it, but it’s worked for me so far. I include the price in my listings when I can, because even though I might not get the “I’m just browsing” users onto my page, I get more conversions: only those really interested, actually come on board. It weeds out people that can’t pay the price range that I list, and they would not have end up clicking anyway.
