Though CareGuide manages nearly 30 sites (see here for a full list), all of these do operate separately. This means that if you purchase a subscription on one site, it does not apply to all sites.
If you would like to unlock the subscribed features available on multiple sites, then individual subscriptions would need to be purchased for each site.
At this time we do not have subscription bundles available. Additionally, full pricing details for each account can be viewed during the account creation process on each of our sites.
