I noticed this plug-in to import csv: "CSV to WordPress Import Plugin" for an extra $10.00 by CodeCanyon. Will this work with this theme?

I need to do the same thing. We will give very basic free listings, and the customers can upgrade their listing with additional information for a small fee. Is this possible with this theme?
