Why would you voluntarily give Amazon all of your sales data? They'll aggregate it, mine it, then use it to optimize their store / pricing / products. At least with PayPal, I know they won't be using my sales data against me.
You didn't read what I said. If you're selling cheaper socks, you're going to lose to amazon and walmart. If you sell new innovative products, you aren't going to lose to them.
Also, with paypal, they get your sales data, sell it to others, AND then just keep your money and close your account.
