Item Pricing Addon
 

What are all the addons that do this? So far I know of

KC_Items
WoWEcon


are there any others?

auctioneer

Lootlink will remember the price a merchant will give you for an item.

Derkyle at one point had Auction Matrix otu but I can't find it anywhere now. and Items Matrix will remember vendor sell prices. not that I'd recommend those two over KC_ITems though.

;) Cairenn isn't here so I have to fill in. I'm sure you understand ;)

hey I'm not only the author of the kaelcyle mods, but an avid user.
