This mod adds vendor sell values to tooltips for items.
ItemPriceTooltip is an addon that adds vendor sell values to tooltips for items. It uses the library ItemPrice-1.1 that knows the sell values for a large number of items in the game. Furthermore, ItemPriceTooltip records vendor sell values for items in your bag when you visit a vendor if an item with an unknown or incorrect price is found. ItemPriceTooltip is an Ace2 addon and all required libraries are included in the download.
Vendor sell values are mined from Blizzard's Armory and should therefor be fairly complete and accurate. All items that have been discovered at least once are listed on the Armory according to Blizzard. Thus, updates will mainly be required after a patch.
Currently the addon knows around 22.000 items.
