Unfortunately, due to the nature of how our website platform is set up, our website and stores only allow ONE discount code per transaction. For instance, if you have a FREE SHIPPING code and a $ OFF code, these two cannot be combined together; you will have to choose one and save the other for another time. (If you are using a $ OFF or other code that changes your subtotal, please remember that to enable our "Free Shipping on orders of $75+" policy, your subtotal must be $75 or above AFTER your code has been applied and BEFORE taxes.)
