Very cool! I was living in the UK in 1995 and I remember my dad back here in the States raving about this site where he could order any book he wanted and they'd deliver it right to the house!

Meanwhile, we barely had email .... I remember our compuserve address was all numbers.
We came back to the States in summer of '96. My earliest purchase from Amazon was October '97 according to Amazon, but I feel like I'd bought stuff before that. BUT, we had a different email address when we first came back and that ISP got bought out later and we ended up with Comcast. So I feel like there were orders under the previous email address that aren't showing on my account now.
I do remember clearly that when you ordered a book they included a bookmark. And for a few years, they sent presents at Christmas -- Amazon commuter drink tumblers -- found a bunch of those clearing out my dad's house after he died.

They stopped that after 3 or 4 years, I think. They also sent fridge magnets, some of which are still on our downstairs freezer.
