I've often seen people offer coupons for popular domain registars like GoDaddy. How do they work? Is it like a affiliate or reseller?
WHile registering domain before making payment you should enter that coupon code and you will get the discount
You enter in the coupon cope in the coupon box when you are registering you domain and you get a discount. Most people advertising coupon codes are affiliiates.
Coupons on online stores are usually small texts you have to input on checkout to get a discount. Stores create coupons for certain customers, promotion campaigns or their affiliate network. There is a growing market of sites generating affiliate income from coupons. This is because most people look for coupons when they want to buy stuff online.
