It would be nice to filter by a price value/range, such as:
- Price=0
- Price<50
- Price>75
- Price between 25 and 75
Maybe like many retail stores have, with two [boxes]:
Price [low value] to [high value]
Also include an option to filter out products that meet the search criteria but can not be purchased individually (such as datasets and products only included in bundles/collections).
