Before adding any coupon to your shopping cart, please make sure your order qualifies for the discount coupon. Many of our customers try adding them to their order when they don’t apply thinking that the order will process. Any order that is placed with a coupon added is immediately flagged and checked by our system and then verified by a live human. If it is determined that the coupon(s) added do not apply to the order placed, it will not be processed and you will be notified stating the reason. If you have paid through Paypal, you will be sent a Paypal request for the balance before the order is processed. If you paid by credit card, we will charge your card for the difference before your order is processed. If the charge is denied, you will be notified and the order will remain pending until the issue is resolved.
