Promo codes are mainly for online stores. Coupons – for offline business. Although the essence is roughly the same: both a promo code and a coupon give you a discount – on any product or service or on a specific product or group of products. In English, for some reason, the word coupon is used more often. There are discount coupons, coupons for today, first order coupons, free coupon codes, free shipping coupons, free digital coupons, secret sales coupons, printable coupons, manufacturer coupons, rebate coupons, coupons for beginners, 40% off coupons, 20% off coupons, coupons for groceries, coupons on app and so on. Some of them are given for free – to stimulate demand or attract attention to a new store or section of the site, and some are sold on special coupon sites, where you can buy a coupon and come to a specific store with it to get a product or service at a discount, sometimes quite significant.
