C. K. Barrett's Gospel According to John looks like it should be available to buy. Ie it has not just a product page but a price - but no buy button.
I know the collection it's in hasn't been fully unbundled BUT books which are part of bundles are normally available to buy separately even if the collection they're part of hasn't been unbundled.
For example, Classic Studies on the Parables of the Bible (30 vols.) hasn't been unbundled but Bruce's A Parabolic Teaching of Christ and Swete's The Parables of the Kingdom are part of the Gospel Studies bundles M and XL respectively and are also available to purchase as standalone products.
Barrett's work is part of 'Gospel Studies L' and so if things were consistent should be available to buy separately?
