Do partial modules I bought go into the cost of the the full module?

Hello, I'm thinking about picking up one of the adventures that is part of from Tales from the Yawning Portal ( <a href="https://marketplace.roll20.net/browse/bundle/5/tal" rel="nofollow">https://marketplace.roll20.net/browse/bundle/5/tal</a>... ), to try out running a module via Roll20, before investing in the full module. If I buy any of them (priced at around $9 each) would that cost go towards the full module (priced at around $50) like they do at dndbeyond. Or would I then have to pay the full price of the Tales from the Yawning Portal module despite having already bought part of it's contents in a smaller format?

There is no credit or discount.&nbsp;See here: <a href="https://app.roll20.net/forum/post/5052338/tales-of-the-yawning-portal-bundle-question/?pageforid=5054547#post-5054547" rel="nofollow">https://app.roll20.net/forum/post/5052338/tales-of-the-yawning-portal-bundle-question/?pageforid=5054547#post-5054547</a>

That's a bit of a pain, but thank you for the reply, better to know.
