I just found AltOutlet, a market site selling products for alt coins... accepting 20 different coins, selling thousands of products.  Part of all orders transactions are distributed to the charity of choice, selected on checkout. They do not take KARM (yet). Seems like they should... has anyone discussed this before? I vote to request being added to Altoutlet, and will take on that simple task if the community has no objection.

"Ɖ498,391 raised for charities across all currencies to date, at current exchange rates.  A part of all orders is donated on your behalf as part of a group donation to your charity of choice.  We aim to distribute funds weekly, depending on order statuses and the current donation total for each charity. "

The currencies listed are currencies that have previously shown interest in being added to Altoutlet, If you would like to see another currencies here, please drop us a message: https://altoutlet.com/alt/contact."
