There is a load of items they could sell as bulk at a discount. So what if I buy marked down 10 pack of bookcases and sell two in game for gold. Like handing out free crack and they will have to go to the dealer for more, LOL. There are those players that think the monthly fees and upgrades are more then enough of a charge. Anything that has an effect on a players combat effectiveness should not be sold. Only earned in game. I could go on about wood armor, bows, and mining gloves that without a certain cash item could never be had by poorer players.
Selling is a good thing if it all goes to the game and not another. Sell a gypsie wagon code that can be locked down in a house that has 6 containers on/in it that don't count towards a house locks for $50. There should be a butt load of cool flashy items sold in the store that in no way can improve how fast, accurate and damaging a player can be. Nothing sold and not earned in the game should allow a player take a 500 point or more item and enhance it no fail. Now if that tool allowed my fisher to change a deermask into a tricorne that would be different. Know how soggy a pelt gets during stormy seas? Sell items that cater to our vanity and not voraciousness.
