http://www.dvdsoon.com/terms-of-use.xml
All rebates can be applied to products only and to a maximum of 50% per order. Since credits can be used on products only, all other charges (e.g. shipping fees) will be applied to your chosen method of payment.
Furthermore, for a limited time, obtain a discount of 3 % in the form of a rebate when you place an order for $100.00 CAD and more. Please note that the discount will be issued when the order has been completely shipped. This discount will be applied to your next order at the time of shipment.
