Outpost's Tip Jar for Ghost
Outpost lets you accept donations of any amount from readers via Stripe and Paypal. This lets your most loyal readers support you even more, and allows you to collect one-off donations from occasional readers.
Publications find that this is more than nice, it actually provides a substantial new revenue stream without any extra work. A number of our sites collect more in donations alone than they pay for our services. Recently, a publication received a $10,000 donation!
We don't take a percentage, letting you keep all the money donated via the Tip Jar.
Feel free to try it out!
