There are different types of coupon codes and some of them can only be used once by a single client. This means that you can not go back to the same online shop and use the same coupon code. You will find that shops such as amazon will offer Nordstrom coupon code that are known as one-time-use coupon codes. One thing with this kind of coupons is that the seller will be able to track the usage of a coupon code and it does this by registering the IP address therefore, there is no way the same IP address can be used by multiple online shoppers for the same coupon code.
If hostgator is offering Nike coupon code and a company has several IT specialists who are hosting different websites then they might have a problem when redeeming the coupon codes. If you work from the same network or use the same computer and all of you happens to enter the same coupon code it will not be applicable and only the first customer who will get the discount. This can be very frustrating since only one person will be able to take advantage of the offer that could have benefited all of you. Instead of using such coupon codes it is advisable that you search for other coupon codes that are not restricted. People can use coupons to get discount on their order, they can apply the coupon codes at checkout.
