Amazon can be charged back...
I'm aware, and I know that's a pretty popular scam; I pay for mine with cash however. I don't have a bank account, so it's kind of harder for me to obtain bitcoin, so I simply pay for giftcards with cash at stores then exchange them with someone on bitmit for a little bit of coin. If it helps, I'm building up a really nice rep on that bitmit account (as you can see) and I've also traded with members of this forum before who I'm sure wouldn't mind vouching for me. Thanks for the view, though!
