I see Verbum has the first two volumes of Baker Academic's Old Testament addition to their CCSS on pre-order. It appears Verbum is going to more or less offer them in a similar timeframe perhaps as when Baker Academic puts the physical volumes out.
So far I see Wisdom of Solomon and Ezekiel for per-order. But if look at the page https://verbum.com/product/252803/wisdom-of-solomon it has a blue box titled "Enhanced for Verbum" and it lists "Verbum Edition $20.99" alongside "Verbum Edition (Group) $20.99". Given they are both the same price I can't figure out what the difference is? Is the Group version somehow tied to the intended full set of yet to be released OT volumes that will eventually complete the entire CCSS?
