yeah, it's difficult to get screaming deals, unless it's a not so common item, and even than sometimes there's interest.. but i have gotten some smoking deals.... and you can generally get new sets of sockets, wrenches, screwdrivers for 1/2 truck price or better... but as I've mentioned recently, the amount of arsehat's that want truck prices for snappie stuff on eghey is thru the roof these days too... straight out of the book prices...
i always have a list of individual items i need to replace in sets that got lost, etc.. socket here or there, stuff like that.. so i watch pretty religously..
i have found stupid good deals in there tho, on odder things.. $500+ bag of air hammer bits for $45, giant chisels, etc..
