Big Gold from Merchant Rings
This is a really neat Diablo 3 trick that will net you some good gold while you do other things. Most players never realize that the rings and amulets the merchants sell can actually be really good. They can be so good that you can in fact buy the for a couple thousand from the merchant and sell them on the auction house for upwords of 100,000 gold.
All you need to do is just start a game and check the rings on the merchant, if there is a good one then buy it and list it on the auction house, if not then just leave and start the game again. Repeat this process until you get 10 rings that will sell for good gold on the auction house then list them all and watch the gold roll in. Sound easy? Well it is!
