We use your email to correspond with you to confirm that your order has been received and another email to confirm the order has been shipped. If there is a problem processing you order, address error, card number etc we will first try to contact you by email. If you place an international order and do not include a valid e mail address your order will be placed on inactive status until you contact us again. We do not wish to incur the overhead of making international phone calls to clarify credit card issues or other problems with the order. We strive to maintain the lowest prices anywhere which is pretty stiff competition. We do this by streamlining our overhead and running an efficient supply and shipping department.
