Amazon tried their own delivery service once. It was called Tote, and it was only available in Seattle.
I do wonder if this isn’t like a Webvan situation though. You could argue that Webvan was a good idea, it was just poor execution and perhaps before its time. Now Amazon (and others) are tackling the same thing — and Amazon happens to be doing it with many former key Webvan people.
In this light, it’s not hard to envision a word where AmazonTote gets resurrected…
