I have an inventory and bank full of items and I have gone back and forth between various traders... however... there are just too many traders and I have seen so many different prices.
How can I know in advance where I will get the best price for items?
Are some traders better for some and others better for others?
And next, buying - again, too many traders to know! ... I have managed to find one site/guide that lists various items, however, is there any general advice I should know?
