It’s because there are gold communities that have large amounts of excess gold on very quiet/dead servers and will help people obtain t3 sets/tabards/toys/mogs/mounts for cheap after you pay them a finders fee.
Here’s how it works
- I want X item.
- They ‘find’ X item on a dead realm, you pay them a bidding fee+finders fee on your realm, let’s say 50k Finders fee for a pair of boots and 100k for bidding.
- You create a trial character/level 1 on the said dead server with the piece you want(T3 doesn’t require level 60 to add to tmog), they trade you 100k and port you to the BMAH.
- You bin mid, if you win bid for min, you give them 90k gold back and they give you back 90k on your server and keep your finders fee. If you aren’t successful (go over bid cap) they give you full finders fee and bidding gold back on the server.
It’s a really great service.
