Pulling costs and number of seats ordered for flex

I'm trying to pull information into an Excel spreadsheet for a flex package that people ordered this season. I need the number of seats and the price they paid. It'd be great if I could pull it into the mainstage information that I can access but that's on a custom tab and I don't know how to combine the two without having another custom field built on that tab. Any ideas for a low-tech human? Is there a report that I'm missing that can retain this information?

Thanks in advance.
