I have a question about the offerCount item within an AggregateOffer type.

I want to show the "true" price range of every product in our inventory but we don't automatically load them all to the page. Most implementations I have seen that trigger the price range showing in the SERP have the individual offers marked up further down the page as well, but that wouldn't work for us. We show 10 or so out of 100s.

In my mind there are two options here. We can use the true aggregate price of the set and skip tagging up individual offers. Or we can tag up the offers displayed but still show what I am calling the "true" aggregate price. Any opinions on whether Google needs the individual offers tagged up? And any opinions on whether the individual offers tagged up need to "match" the aggregate offer prices?

THANKS
