It’s simple for younger and/or unemployed folk. Get your parents to send you to the stores whenever they want to buy something and ask for small change, accumulate enough and you might even buy Live+. Or fix something in the house, parents usually give something, mostly money, when they are happy. And, be honest to them about it. Just worked for one of my friends here on IF. Good luck.
I got live+ for my birthday:)
Google Opinion Rewards is awesome too :)
