Seriously, this. I just checked my Quidco account - I've made £283.13 cashback via Quidco in the last two years. The vast bulk of that from big ticket purchases (e.g. flights, hotels) where I've remembered to log in to Quidco first.
By contrast, the amount of money I could make from recommending books, movies etc to friends via a Referly would be in the pennies.
To sum up: Quidco, I just remember to login before I buy a big ticket item, and literally make hundreds of pounds. Referly, I have to convert all of my product links to Referly affiliate links in the hope of making pennies.
They have a Firefox add-on too, which brings up a little bar at the top of the page when you visit one of their partners, advising you that you could earn cashback.
