AIDS Marathon is double-charging some of my donors.

Two friends have reported that when they submitted their donation form online, the site said that the submission did not work, so they pressed the "back" button and resubmitted. Later, they found that their cards had been charged twice.

In both cases, they decided it was for a good cause and did not ask to be refunded. Still, it is a problem because I don't want the people I ask to support this cause to feel like they are being taken advantage of.
