In video games, regardless of a vendor NPC's specialization and location, they will never refuse to buy items from you. And they will never run out of money. That's right, a bread baker in a poor village will gladly pay you for anything from Vendor Trash to the Infinity+1 Sword, as will a renowned shield crafter in a capital city. What exactly do they do with these items depends on the game. If you're lucky, the same vendor will offer them for sale at triple the price (even if it has nothing to do with the items they usually sell); otherwise, they will vanish without a trace and be gone forever.
