If you are looking for a Hostgator coupon then there are high chances that you have found hosting that you need. However, that does not mean that you will be able to find a coupon that suits your hosting needs. There are simply some coupons that are more suitable than others.
Coupons that are able to offer a set percentage off will often have a condition somewhere. You will usually find that you have to spend a set amount of money on the hosting or you will need to buy a certain plan. You should check for this condition before you decide that that is the coupon for you.
The ones that will offer a certain amount off will usually be aimed at you buying certain plans. This will often involve spending a certain amount of money first, which will be written somewhere in the small print; you should check this before you commit yourself to using it and buying something that you do not really need.
