Related question:

What is the minimum sensible charge?

Stripe's front page advertises a fee of 2.9% + 30¢.

Crowdmatch    Fee    Total  Fee/Total   Fee/Crowdmatch
-------------------------------------------------------
\$0.10     30¢   \$0.40      75.18%          302.90%
0.20     31     0.51      60.46           152.90
0.30     31     0.61      50.71           102.90
0.50     31     0.81      38.61            62.90
0.80     32     1.12      28.77            40.40
1.30     34     1.64      20.62            25.98
2.00     36     2.36      15.18            17.90
2.10     36     2.46      14.67            17.19
3.40     40     3.80      10.49            11.72
5.50     46     5.96       7.71             8.35

Based on that table, I think \$2.00 is the minimum sensible charge.

I suggest we specify it as a maximum fee percentage, however, to help
adapt to future fee differences. That being the case, I propose we
choose 15% as the maximum fee percentage (plus or minus some tenths of
a percent).
