Promo code - What are coupon codes?
You will come across two main kinds of online promotions while shopping. One of these is the "coupon code" otherwise known as the "promotional code" and the other is really a "link only" promotion. Either of such options might be provided by online merchants as promotions.
How do I 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 require for the web store) and will acquire the discount as you take a look at.
