Amazon has this thing called amazon shopper panel . https://panel.amazon.com/ . where you can do a few VERY easy task, every month you get the chance to upload 10 receipts for guaranteed amazon balance. have used this for months and have made
Things you can do
Surveys: the surveys take seconds to complete for 0.5$
passive: you can make money passive not a lot but done through amazon tracking what ads you see i think
receipts: uploading receipts is the main way to make the quick buck
unfortunately this is isn't scalable you will make 10-20$ depending on surveys you get. something worth doing for the little effort and time you give
Enjoy!
