From time to time we issue special promo codes that give discounts at checkout (just because we can!). We reserve the right to end these promotions at any time should we deem it necessary. In addition, promo codes may not be passed from person to person without our permission (email us, we usually don't mind at all). If you are unsure about the validity of a promo code you have, then feel free to email us and check if that particular promotion is still running. Promo codes with a minimum spend requirement will not work until the contents of your shopping cart reach that total - you can enter the code any time after the minimum spend has been reached, and the code will be applied retrospectively to everything in the cart. If you have any problems, then just include the details in the comments section of your order, and we will happily fix it up for you. Only one promo code can be used per order.
