ebay search is really crappy / broken and not replicatible. I think it has to do with it being a huge distributed system, data existing on different servers, and some data being cached. recently saved searches have been totally random, I get results like every few days at random times, it used to be at the same time every day.
totally unrelated, but they broke the mobile interface recently where you can't use the "classic" site and it switches back to the mobile version after you log in. Really pissing me off.
