At my grocery store today there was a large sign at the checkout informing you they don’t have coins to make change, please use electronic payment.

If you pay cash and don’t have the exact amount the total will be rounded up and the excess donated to a charity.

As long as that charity isn't the owner of the grocery store's yacht club I like this idea. In practice, though, the types of charities usually offered are a) the business themselves like Goodwill, or b) controversial at best (say, a Komen-eqsue figure). If there was a way to make this choice with less friction I'd be much more willing to give up change entirely.

IIRC it was a local food bank.
