I'm trying to make a purchase. The pay button is grayed out with all payment methods. I'm on android, and I've never had trouble making purchases before.

I'm really starting to hate this fucking site.

Ugh. It was user error. I was buying a DLC for a game I didn't own. I do have it, but on another service.
