After fighting for weeks trying to implement in-app purchases using Google billing, I'm giving up and taking it as a sign that, as a Bitcoiner, the right decision is to add Bitcoin payments.

What is the best (intuitive UI/UX, simple implementation, low maintenance, low fees, etc.) way to go about this?
