Webvan is a famous example. I still remember their commercial, which showed a couple hiking through the woods when one of them experienced nature's call but found out they had forgot to pack the toilet paper. Place your Webvan order and by the end of the commercial a van had showed up and the obliging driver packed one roll of TP out to the couple and saved the day.
The reason I remember that after 15 years? Because I was sitting there watching the commercial wondering how Webvan was dumb enough to think it was going to make money off people who needed things like 1 gallon of milk, or a pack of TP.
Wash.io sounds a lot like that.
