I reallly like the ease of use and speed of the addon, though I encountered something annoying today when I was trading with a friend of the opposing faction through the neutral auction house.
We both exchange a bunch of horde/alliance-only vanity pets and cooking recipies for 1 copper to then sell them in our own auction houses. The problem: AuctionLite won't let me start auctions with a buyout price lower than the vendor price, even after fiddling with some of the settings for minimum profit and vendor price. I guess it's nice to be warned if you are selling something way too cheap, but you should at least be able to do it intentionally (and putting up ~100 pets manually just plain sucks
).
