The company Washboard
launched just recently. The concept was that it was a subscription service for quarters. If you paid them $15 every month, they'd send you $10 in quarters in return. Most people, they assumed, would use the quarters at laundromats.
The company lasted less than two weeks before calling it quits. They ran into problems with their payment processor. Also, by their own admission, reactions to the concept were "mostly bad".
