In order to provide the best customer experience, we mark products “low stock” which are low in quantity with manufacture or supplier. Should a customer choose to checkout with “low stock” products in their cart, they may receive a call from our sales department about the product not in stock and potential alternatives. Discounted Wheel Warehouse only authorizes credit cards at checkout; we do not charge the full amount until we confirm the delivery with the manufacture or vendors. Thank you for shopping with us!
