It costs about $35 a month in serving fees, SSL license, code subscriptions, and so on to run the site.
I am deprecating Paypal, meaning it will remain active as long as old subscribers exist. But I request new subscribers and donors use the methods above, which use Stripe as a back end. It’s securer (note the HTTPS on the URL bar in your browser), easier on you, and you don’t have to deal with Paypal, and any credit card may be used. Or cash in small brown envelopes may be handed off to me. Email for arrangements.
