Spek is right:
I actually canceled my prime membership that ive had since '08. Prices were not as good for some of the books I was looking at. Plus, late last year I took their seller app and scanned in a dozen or so bar codes at the store and they were either in line and not worth buying at the store to arb the diff or were not allowed to be sold on prime.
On twitch all i lost was my prime sub. Sometimes I view adverts in a separate browser thats muted and give away the bits I get for them. They do throttle me sometimes but you can usually get 2-3 bucks a week depending on how much they give you. Each advert can give you 5, 10, 50, 75 bits randomly and are worth a penny apiece. You can pass them out to anyone and split if you want to.
