I remember the days before Amazon. When the thought of getting something physical from a place that only existed online was unreal. Then I remember when Amazon only sold books. And day by day, month by month, they started offering more.
I remember when Amazon launched their Prime subscription with included 2-day delivery back in 2005. Immediacy became paramount for a sale. If you needed something, you went online, you found it, you bought it, and it was on your doorstep in 2 days. Now, it's there tomorrow or even later that afternoon.
