Bump is letting users send paid apps (on Android)? (groups.google.com)

Bump does not allow users to share paid apps for free. All we do is share a link to the App Market so your friend can find the app (and hopefully purchase it) easier.

The key part of this post is: "(I haven't tried actually sending the paid app, so maybe it fails at that point - can anyone confirm? I hope to be proven wrong here)"
