Ah right!
I want to thank Cyrus for pointing me to the links for
Auctioneer and
Lootlink, two excellent mods.
They provide a bunch of information on items in your inventory or you search through any of the items it knows about. Information such as how many of that item is up for auction, what the starting bid is, what the buyout bid is how many have bids on them, etc. It will also provide vendor information, such as how much a vendor buys and/or sells that item for.
Installation is pretty darn easy, just unzip the downloaded files into your WoW directory and they'll drop into the appropriate spot within
Interfaces/Addons.
I typically do a
/lootlink scan when I log in. It takes just a few minutes and that's a great time to chat and catch up with people.
Enjoy and I hope you find them as useful as I have.
