Cashback - What are discount codes?
You will find two main types of online promotions when shopping. One of these will be the "discount code" also referred to as the "promotional code" and another is a "link only" promotion. Either of those options might be available from online merchants as promotions.
How do I redeem a "linked" coupon or product?
These do not contain a real coupon code and need to be activated from the special link. You receive the discount after clicking this link (which will get you for the web store) and definately will acquire the discount when you take a look at.
