I use a program called Perk, along with 5 cheap ass phones to earn Amazon gift cards. I used to use SwagBucks and mTurk as well.
I bought my PS4, PSVita, and lots of other things with the money I earned from SwagBucks, mTurk, and Perk.
I started Perk in September, and by the end of the year I had made $500 with the one program.
