I'll wait up to a certain point. I prefer to buy from Eden but I'm also pretty impatient. I can entertain myself with other things but if something is topping my wish list and it looks like Eden isn't getting it anytime soon, I'll get it somewhere else.
I also sometime buy off site if I can get a better price than Eden by more than 40% (so more than what I could get by doing a buyout). I don't like to buy from other sites and it doesn't happen very often, but I have to watch my money!
