What is the max number of retainers?

Again, it's not how much it costs that is stupid. It the fact that it's a subscription where one "perk" is that you are allowed to purchase another subscription, and that "perk" is only really available if already maxing out all the other related subscriptions. It's a ridiculous way to set it up. Just bake the cost of the additional retainer into the app subscription where it just gives you the additional retainer would make far more sense.
