At this point, you’re probably used to buying pretty much anything and everything from Amazon. But once upon a time, you went to Amazon and entered your credit card for the first time.
And you might not know this . . . but you can find out what you bought that day. Go to Amazon.com, go to the “Your Orders” section . . . and you’ll see a little dropdown box where you can choose to see your purchases from every year.
Pick the earliest year, and it’ll show you the very first things you ever bought.
