TopCashBack is basically a Cashback site. Long story short you decide to shop somewhere, go to TopCashBack, find the shop and follow the link, then shop as normal. You then receive cashback in your account, you can withdraw it to your bank, withdraw it as vouchers (that often gives you bonuses too) or other options, such as Paypal.
They also run bonuses and games throughout the year to earn extra cashback. You can also add a browser extension to your internet browser too!!

I may receive a referral perk when you use these links. I accept no responsibility for any losses you may experience and you use these sites at your own risk.
