Well I totally found some sort of a glitch but it only works if you have the feast day add-on package....

If you do than you know about the lovely butterfly sword for sten..... If you don't keep on your person you know that it appears in your store back at camp..... well since you can only sell the sword for the first time at like 7 gold stack them away in your storeage chest and then when your almost at the end of the game sell them all and you'll have tons of gold when you are finished.....

When i did this for the first time i think that i accumalted almost 90 swords all together and got a whooping 630 gold more then ive gotten since just playing the game the normally.....

just thought i would let you guys knows!
