We try to make using promotional codes and discount codes as easy as possible, but sometimes people still have questions of why they won't work on their cart, or why it only applies to certain items in their cart and not to others.
When you find a promotional code from us, make sure to read the text around the code as well, as it outlines the terms of use for it.
For instance, our code for first time customers gives 10% off your first order, however that code cannot be applied to items that are already on sale, refurbished, or closeouts. I know that sounds like a bummer, but most of the times that item is already discounted more than what the code would have done.
If you have any more questions, call us directly a 1-800-854-5821, or send us a chat.
