PC to PC Trading

[Archbaron]

The biggest problem I find with pc trading is that players often only want what is immediately codewise useful to them, or an upgrade. May as well leave them to doing runs in WoW to upgrade their leet gear.

This means the exact right piece of specially weighted armor or the hardest hitting most decorated sword.

Yeah, you rarely stumble across the character who merely wants a different colored hat or small, cheap ring they can't seem to find.

The easiest (read: most effortless...not most lucrative) way to make money as a merchant is to act as an agent, using your uber haggling skills to trade shit for other PCs to NPC shops.

Once you're good at it, you can take a 70:30 or 80:20 split and both of you end up with more coin than if the seller had gone directly to the NPC shop.

Take note, players:  that means that your non-haggling, spam-hunting ranger can -still- get 10-15% haggle markup simply by allowing a PC haggler to sell your phat lewt.
