There's a code of conduct that Stripe is an adherent to that mandates some elements of standardized pricing display and so on.
Traditionally, it's been a very complicated process. It's been very opaque. I remember when we were trying to set up our first what they call “merchant account”, we found it very difficult to figure out how much this would cost.
That's why we're so sort of emotionally attached to this idea of simple, transparent, blended pricing that's there on the website and doesn't change with time and so forth. It tends to be very complicated and difficult to model these costs.
