Amazon actually bought a bunch of cryptocurrency domains according to whois. In 2013 it bought the amazonbitcoin.com and in 2017 it bought a couple more. It's mainly for strategic reasons that they do it so if bitcoin does become huge, they can still be on the forefront. I would venture they stand more to benefit from stablecoins though.

Also, one of Amazon's competitors - Overstock - also issued Ravencoin, which is a PoW similar to BTC. Overstock's team is very bullish on cryptocurrencies as a method of payment and differentiation in the ecommerce space.

Currently, there's ways for people to purchase amazon gift cards just with BTC through Bitrefill as well: https://www.bitrefill.com/gift-cards/?hl=en

Hi,

I would like to buy $200 worth of BTC with Paypal. Would like to trade with someone reputable and am willing to work on reputable person's terms.

I also happen to have some gift cards which I don't need from Rue21 (clothing store [$100]) and zappos (online shoe store if you need shoes [$150]) if anyone is interested.

Kind regards, pm me your terms. Open to escrows.
