Sure thing, that's been processed.

It is a bit of a limitation of Snipcart at the moment, it would be nice to have a way to specify an amount dynamically. While that could happen in terms of _adding_ it to the cart with some Javascript, the problem is that Snipcart does come back to check that the HTML on the page hasn't been tampered with before placing the order (otherwise someone could edit all the prices before adding things to the cart).

Community Store does have the ability to handle things like donations and ad-hoc payments where the amount is entered.
