If we find that the records that you requested have already been digitized and are online, then we will refer you to that site(s) at no charge.  Most of the web sites for such online records are free.  Some require a subscription fee but, in those cases, there are a variety of legal ways to access them for free as described in THIS blog post.
If you prefer that we obtain online records for you, then we can do so for a nominal fee which will be quoted to you in advance for your approval.  This nominal fee is required under the Terms of Service for our subscription to such sites.  As with offline records, our fee covers the effort that it takes to find and retrieve the online records, not for the records themselves.
