It's exciting to see this!

It's cool that small independent operators start accepting BTC and alt coins... but the big step towards more "mass market" adoption of cryptos will come when millions of people start seeing the "Bitcoin accepted" on their checkout pages.

I'll certainly add my voice, and can even do so (as an amazon marketplace seller) with the additional incentive that "Our customers are asking for this, so you're potentially losing sales not having it as a payment method." I'd encourage any other amazon sellers to do the same!
