We are having a few problems with discount codes, some cause the error "order invalid or failed" at checkout; if this happens please delete the discount code and place the order without it.  We will then take the amount off manually for you after being informed.  We are sorry for any inconvenience this may cause and this will be fixed asap.

If you wish to pay via Google Checkout or PayPal without signing up to either of them, please click proceed to checkout and not the buttons for them as they are for registered users quick checkout only.  Thank you. ^^
