From Caitlin C:
One other thing I noticed, in the context of looking up gifts of $10k on donate wiki, is that we suggest PTF to the donors giving $10,000, meaning if they select PTF, they'll get an error on Payments for trying to process a donation of more than $10k. Could we change the PTF rules so that donors giving > $9615 don't get the PTF option?
This is very much an edge case, but might be worth fixing in banners and donatewiki
