Currency
Prices are in US dollars. If you shop in another currency, prices are converted for display and the amount charged is the amount shown at checkout in the currency you selected. Applicable taxes are added at checkout. We are not responsible for currency-conversion differences or fees charged by your bank or payment provider.
Price at time of order
You are charged the price shown at the time you order. We do not raise the price of an accepted order except as set out in the Pre-Order Terms and Tariffs.
Discount codes and promotions
Any order placed using a discount code is final sale. Promotions announced after an order is placed are not applied retroactively, and discount codes cannot be added after checkout.
Pricing errors
If a product is listed at an obviously incorrect price because of a typographical, system or supplier error, we may cancel any order placed at that price and refund it in full, even after the order has been confirmed.
