I've been using TopCashback on and off for about a year now, and I've earned £110 just from clicking through their website to shop online instead of going straight to the website I'm shopping on. It's easy money so thought I'd share my code with you all! Click here to be taken to the sign up page.
There are hundreds of retailers on there. It's especially good for bigger purchases like holidays (e.g. 8% cashback on some hotel brands, and 3.5% on LoveHolidays which all adds up nicely) but it also adds up when you use it for smaller purchases (loads of brands on there for clothes, toiletries, food, health and beauty stuff, etc).
FYI if you join through my referral link, you'll get a bonus (I think you get an extra £10 once you've earned £10 in cashback) and just to be transparent, I'll get £25 for referring you once you've earned £10 too. 😁
