Set against a M$ 2.8 project, this comes to a prorated share of about $3.92 / $1,000. Plus another 50%, $5.88 / $1,000 total, to ameliorate the responses of some. With a debit card included to allow access to the money, it is a significantly better deal than a wire transfer fee.
Thanks for taking the time to do the math. I'll be making my $5.88 per $1000 received donation.
