I don't know why this is or if I'm just dense but when I try to buy camp supplies(for example, I've tried other things) from inn at Vale or the blacksmith it won't let me purchase it even though I have the money to buy it. It will show the item with the amount required to buy but when I click on the "trade" button all that happens is the coin dropping sound and nothing else. I don't get the item, I don't lose money. What gives?
