Auction House is a trade place for each WoW player in World of Warcraft. It is very useful and convenient because it can help gain cheap items and Mabinogi Gold without trouble. There are Four tips for players how to buying items:
1) When selling an item, look at how much other items of that same type at that level are selling for. It could very well be that Rings of the Muskrat are selling for 12g, 11g and 10g.
2) Do some lookups at your favorite site and find out what all those white items are for. I've tried selling Coarse Gorilla Hair, and Gorilla Fangs on the AH. Nobody wants 'em. Same with Wicked Claws.
3) Find out what white items are in *high* demand, and don't be afraid to farm for them. I was amazed at what Scorpid Scales were going for on my server. If I felt my Paladin really *needed* a lot of WoW money, and had I wanted to do it, I would have farmed Scorpids for skinning for a while, and made good money.
4) Don't be afraid to undercut, but try to avoid 1c undercutting. If I see someone doing that, I will pay for the higher priced item. 1c undercutting is rude and less attention-getting anyway. If I *do* do that, it's pricing something at 9g99s99c, just because I like pricing things like that.
