We require no coupons or any other action on your part; just submit an order over $135.00 and the discount will be automatically reflected on the invoice you receive with your order. The invoice on the web from Yahoo Stores does not show the discount, but in an effort to provide you superior customer service we review each and every order to insure that our fulfillment and billing is correct. At this point we apply the 10% discount for all orders over $135.00 and enclose the revised invoice with the order. Easy isn’t it?
