In order to decide whether or not to buy a commentary or series of commentaries, I would find it a big help if I could study a legible selection of several pages from the book or at least the series. You do sometimes give sample pages, but I find them hard to read. If you could give the opportunity to view 20 or 30 pages of a book or from the series, this would be a big help. Maybe something like Acrobat format. If you wanted to make it impossible to save on one's own computer, that would not matter, but it would be a help to be able to study it at leisure.
I spent a lot of money on the ICC OT commentaries, and then found the UBS commentaries were much more helpful to me, as well as being less money. You would have had less immediate profit, but a much more satisfied customer if I had been able to examine both series thoroughly. And I might well have bought more books if I had been able to preview them.
