If you buy a lot of things online, then these websites can be really useful. They work in different ways. A voucher code website will give you a promotional code that you can enter at the checkout when you are shopping online. This will give you a discount on the item that you are buying or free postage. Therefore whenever you are buying online, it is worth searching to see if you can find a code so that you can save some money. You can easily write ‘discount code’ and the name of your retailer into your search engine and find one that way. However, you will find that there are some websites which have a really good selection of voucher codes and so once you know where to look, you will be able to visit the specific website and search for the codes there. You could save a certain percentage or lump sum off your shopping or be given free postage or other incentives.
Cashback sites sometimes incorporate voucher codes into their sites as well, but generally work differently. You need to register on the site and open an account. Then when you want to buy an item online, you follow the link on their site to get to the retailer. Once you have done this you buy as usual. Your purchase should be tracked by the cashback site and once the retailer is happy that the transaction has gone through properly they will pay the cashback site commission which will be passed on to you. You may have to accumulate a minimum amount in your account in order for you to cash out the cashback that you have accumulated. Often it is paid straight into your bank account.
It will take some effort to sign up and you will have to remember to click through the site every time you make a purchase if you want the cash back. You will also find that some do not track properly and you will not get money back from them. However, overall it can be a really worthwhile thing to try. If your cashback does not track then you have not last anything apart from a few seconds clicking links and if it does work, which is usually does, then you can get some extra money when you shop.
The only thing that you need to be careful of is combining voucher codes with cashback. Most companies will not allow you to use two offers at once and so if you try, you could find that you do not benefit from either. If the cashback site says you can also use a voucher code, then it should work, but if you try a voucher code form one website and cashback from another, it is likely that neither will be successful. Therefore choose the one which will benefit you the most.
