This is not only a way to make money but also to save money as a student. If you look at it in a different way then you are making money with every purchase you would have made anyway, whether it be 10% or 0.5% cashback. There are a number of cashback sites out there which pay you the commission they otherwise would have earned. We recommend signing up with Top Cashback, Quidco.com and Swagbucks which are free and offer the best selection of retailers and exclusives.
