What are promo codes and how do they work?

Promo codes (also called coupon codes, discount codes or voucher codes) are short alphanumeric strings that unlock a discount, free shipping or a bonus gift when you enter them at checkout in an online store. They are the digital equivalent of paper coupons — one code, one saving, applied in a single click.

On Promocod every code is hand-checked and refreshed multiple times a day across hundreds of brands and thousands of shops — from fashion, electronics and home to travel, hosting and food delivery. Alongside code-based offers we also list "deals": public promotions that need no code, just a direct link to the discounted page.

Using a coupon is simple: pick an offer that matches your basket, copy the code, open the store, paste it into the promo field at checkout and confirm — the price drops before you pay. Coupons can be limited in time, quantity or by product category, which is why we mark exclusive, hot and expiring offers so you always spot the best saving first.
