Haha, sometimes the US-European disconnect is very cute. I mean no offense, but checks went out of use in my country like 20 years ago. (Anectodally, they can still be cashed, for a service fee of $30 or so). Oh, and mailing something to the US would alone be more than PayPal's cut.
So your banking system has no way of giving money to an organization you want to support, and you're calling us "very cute"? That makes a lot of sense.
