Do you have the Traveler’s Tundra Mammoth? Make gold by selling the vendors!
If you have the Traveler’s Tundra Mammoth you can make some world of warcraft gold by selling your services to other people in the wilderness.
You can ask them to pay you for allowing them to repair or buy reagents from your vendors on the Traveler’s Tundra Mammoth.
You probably won’t be able to make much wow gold this way, but every single gold counts.
