Should I even do product page schema?

[SearchStan]

If I have no reviews/ratings on the page itself and special/limited time offers and just a regular product page with a standard price, is there any ability to do product schema with it getting flagged for errors?

Google's Structured Markup Testing Tool threw me an error when I test it without any of those:

| One of offers or review or aggregateRating should be provided. |

And even if it's possible, is there any point?

Couple of questions.

1. Are the aggregated reviews going to be for the entire site or just that single product?

2)Do you plan on having multiple people be able to review each individual item and are those reviews coming from users of the site or a third party?

3)How many products/pages do you have?
