Promo code - Exactly what are online coupons?
You will come across two main kinds of online promotions while shopping. One of them will be the "discount code" otherwise known as the "promotional code" and another is a "link only" promotion. Either of those options could be offered by online merchants as promotions.
How do you redeem a "linked" coupon or product?
These usually do not contain an actual discount code and need to be activated with the special link. You get the discount after clicking this link (that can get you for the web store) and will acquire the discount as you take a look at.
