What level are you? Paladin Ro armor isn't the most expensive things in the world and generally when you do see them being sold the prices are wildly all over the board because there aren't as many people who are looking to buy them which makes for some prime haggling if you're the charismatic type of person.

With that said, start looking into the sisters camp in Lesser Faydark for their weapons and gems they drop. If you spend a few levels at them you can actually make a legitimate amount of money. Certainly enough to buy quite a few pieces of your Ro armor.
