Cashback Kings is one of many cashback sites and one of the better ones. These sites pay you whenever you buy something using a link from their website to another and they pass on some or all of the referral money on to you the consumer.
Cashback Kings is a good cashback site as they pass 100% of the money they receive onto you and also are now free to join (unlike a site called Quidco which you have to pay a £5 fee per year to use.) Cashback Kings get their money through advertising and they also promise to match any other cashback site percentage if you can find a better one.
There is also a referral scheme where you earn £1 when your friend earns £5 and you can chose whether to keep the £1 or be generous and give it to them to get them started!
The site is nice and colourful and is presented well.
The minimum payout is only £1 and you can be paid by Paypal, BACs or in Amazon vouchers which gives you the choice whcih is nice.
Overall I think Cashback Kings is a nice cashback website but has a few problems so I personally would recommend this site but recommend Topcashback if you have not joined any cashback sites before as it is overall better even if it has a worsedesign! (ask me for my referral link if you want to join!)
So go on earn money just by sitting on your sofa and shopping. I know lots of people who would!
