The Basic membership provides 200 coins per month. This is likely the subscription you’re already used to! You can use your coins to purchase episodes of your favorite text stories and webcomics, as well as audiobooks that are not exclusive to the Radish PLUS catalog.
The Radish PLUS membership provides unlimited listening access to any of the Radish PLUS titles (meaning you do not need to use coins to listen), as well as 100 coins per month, which you can use for audiobooks not part of the Radish PLUS catalog, or for purchasing episodes of that awesome story you’ve been reading.
Audiobooks that are exclusive to the Radish PLUS catalog can’t be purchased via the Basic membership.
TL;DR
Basic = 200 coins per month. These coins expire at the end of each monthly billing cycle and are replaced with a new set of 200 coins. You have the ability to purchase audiobooks on an individual basis using coins, as long as they are not part of the Radish PLUS catalog.
PLUS = Unlimited access to the Radish PLUS catalog + 100 coins per month. These coins expire at the end of every monthly billing cycle and are replaced with a new set of 100 coins.
