Sorry to hear that you have trouble with the discounts. First, please note that only one discount can be applied to a single product to ensure you get the best savings. (Special Offer & Clearance items are not eligible for additional discounts, but they're already super affordable!)
If the item you want to purchase is not under Special Offer & Clearance, and it's the only discount on your checkout, but the issue persists. Just submit a request here by sending us a screenshot of your checkout and your discount code/detail, our friendly team will be more than happy to assist you.
