Once an order is placed, we are unable to manually apply coupon codes. The good news is that your WELCOME10 coupon remains valid if you have subscribed to our newsletter, and you can apply it to your next purchase. Simply enter the code at checkout to enjoy the discount.
If the code appears at checkout but you are not subscribed, the system will automatically remove it. For this reason, we recommend subscribing to our newsletter before placing your order to ensure the code can be successfully applied.
