Discount codes must be applied at time of purchase. We are unable to retroactively apply them to orders. We do not offer refunds for discount codes that were not applied correctly.  We are not responsible for giving out retroactive discount codes and can not provide new ones. Only one discount code can be applied per order and cannot combine codes. If you are having an issue getting your coupon code to apply, please contact our Support via email or phone before placing the order, we will assist to the best of our ability.
