Sometimes products are excluded from our promo codes, this typically includes bundles and various other items. The reason for this is because we have already marked down these products at such steep discounts, as well as offering free shipping, we have excluded them from additional savings. If you believe that the promo code you used wasn't accepted in error, or you forgot to input your promo code before checking out, please Contact Us and provide your order number and promo code name and we will be happy to look into this for you!
