Can you use this with Paid Memberships Pro?

I’m using Paid Memberships Pro to sell access to posts on my site. Users are not actually downloading any files, they are just given access to read posts.

I’ve already got PayPal Express Checkout set up and working with PMPro but then found out about PayPal Digital Goods and the lower fees. PMPro doesn’t seem to be supporting it directly so I’m looking for a solution that will work. I looked into how to integrate it but it’s all completely over my head and I’m afraid to cut and paste code, not knowing what it will do and how it will work with PMPro.

Can I use this plugin to work with PMPro? How?
