I assume many other educators and pastors are in the same boat. I recently wanted to buy the NICOT for Ruth. The whole set goes for over a thousand dollars. Why doesn't logos add the feature that iTunes uses. If I buy Ruth Individually, then later decide to buy the set, the price that I've already paid for the individual titles is applied to the whole set price. For example, I bought 4 books in the NIV application Commentary series in the Old Testament, then decided I wanted to get the whole set, the amount I've already paid could be taken off the set price. Right now, for some of your best commentaries, the entry price is too steep. Many Logos already does this and I just haven't figured it out yet, so after looking through the store for awhile I thought I'd post and here others/official responses.
