0.01 Buy Order Bug – Item Disappears After Purchase

A bug occurs when listing an item for 0.01 — if a buyer attempts to purchase just one, the system struggles to calculate tax correctly. This results in a "Buy" button showing 0 value, followed by a popup error. The item then disappears from inventory (e.g., gold pickaxe). Issue reported by multiple users. Needs fix on low-price transaction handling and tax calculation
