A similar idea, but for periodic donations. Sites offer "subscription links" that get a share of your fixed donation budget per month, meaning that if you designate 50 usd per month for donations, all those you're donating to will have to split 50 usd. In addition to that, stripe lets you kick out any subscription from the list. Stripe can also aggregate these micropayments to reduce visa/ACH/whatever fees.
