Premade Module Support - Mines of Phendelver

I tried doing some searching for an answer to this question without much luck. I already own a physical copy of Mines of Phendelver.  I see that I can also buy it via roll20 and then I get all the resources and everything too. Being that I already own a copy of the adventure is there a way to get access to the resources in roll20 or would I have to buy it here/upload them myself from my copy?  (wasnt sure if this was the better place to post or marketplace was)

You will have to buy it here to have all the work done for you or upload and do all the work yourself. If you buy here there are features added (but not enabled unless you are a subscriber) that enhances your game.

This is asked pretty regular so don't worry. If you have more questions feel free to create a post and someone will answer.
