[Bug]: Subscription quantity changes can get out of sync

[dombarnes]

What happened?

If you either rapidly change the quantity with the +/- buttons, or one of the changes is subject to a longer network request time than a later one, (i.e. the change from 10 to 11 arrives after the change from 11 to 12) pricing and quantity can get out of sync with each other.

Steps to reproduce

1. Load the homepage an click Get Started
2. . Rapidly click + a bunch then - a few. See if the pricing and quantity match
   OR
3. Turn on network conditioning in the dev tools and change the network speed

What did you expect to happen?

Correct pricing shows up
