One little tip that really helps when trying to make money is to be creative. Almost every MMO offers players the chance to buy and sell goods. Some allow you to post these items on a global “auction house” while some let you set up your own shop or “carpet”

Having a catch phrase or slogan (just like with a real business) will really draw people in. People tend to remember seeing funny or catchy slogans. Give people something to remember you or your business by.

Something like:

“Bob’s Junk World now open for business. Where one mans trash is another mans treasure! Let Bob’s Junk World take your unwanted stuff and redistribute it to the world.”

That’s a very basic slogan but it works. Make yours fit your game and what you’re welling. Obviously you wouldn’t want to be an armor sales men with a slogan that talks about weapons.
