SETSOFRAN London Frequently Asked Questions
Before using a coupon, always check its Terms & Conditions. If it is a sitewide code and still doesn't work, please report it to info@redeempromos.com. If the coupon requires a minimum spend, applies only to specific products, categories, or has other restrictions, it may not work unless those conditions are met.
We have shared a detailed guide above explaining how to use coupon codes. Simply follow the instructions carefully to apply your discount successfully at checkout.
Most brands do not allow multiple coupon codes to be used on the same order. However, you can still try applying more than one code. If stacking is not permitted, you may still be able to use a coupon code on sale items to receive additional savings.
To enjoy free shipping, check the deals and promotions listed above. Many merchants offer free delivery through special promotions, minimum order requirements, or exclusive coupon offers.
Yes. In most cases, you can use the same coupon code multiple times and on multiple orders until the coupon expires or the retailer withdraws the offer.
