No genuine dollar pricing is published. The vendor's package-comparison page lists four tiers: Community Edition (free, open-source, self-hosted), Growth (SaaS, shown only as "Starting at $0 Annually" with a free-trial CTA — no real recurring price disclosed), Advanced and Premium (both "Call for a quote"). No billing unit (per user, per SKU, per asset, per GB) is stated anywhere on the site for the paid tiers.
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
