Coupon code - What exactly are discount codes?

You will find two main categories of online promotions when shopping. One of these is definitely the "coupon code" also known as the "promotional code" and the other is a "link only" promotion. Either of such options could be available from online merchants as promotions.

How do you redeem a "linked" coupon or product?

These do not contain a genuine promotion code and must be activated with the special link. You get the discount after clicking this link (that will require to the web store) and will obtain the discount while you take a look at.
