The only paid-for plug-in we have across our Atlassian products is JaM (https://marketplace.atlassian.com/plugins/com.go2group.jira....) - for bi-directional synchronisation of defects between JIRA and HP Quality Center (QC). This is because it is a real cost saving for us to not purchase QC licenses for developers.
Can you clarify what it is you are seeking a report on?
We run most of the Atlassian products internally. The only Confluence plug-in we have seriously considered purchasing is Gliffy (https://www.gliffy.com/products/confluence-plugin/).
