Do you need to attach a credit card or something? Or can you just make a blank amazon account, a blank twitch account and then redeem a month of membership free?
You need to Attach a Creditcard to amazon, and then get amazon prime, which is free for 1 month, but after the 1 month they will take money out of your Creditcard. Check the General market out (lookout for my thread) people are offering cheap twitch prime accounts.
Amazon offers a 7 day free trail in most countries. You apply for the trail (need credit card). Become twitch prime, claim benefits. cancel Amazon prime subscription/trail. Remove your credit card from the amazon account.
