Some already are aware that a lot of the journal libraries (a series) in Logos are priced 'oddly'. Some, you basically take the per-copy and multiple to get the 'library'. That's no fun.
But some, you take just TWO copies and multiply! I was on one of my many rabbit trails and wanted something from Adele Yarbro Collins. Semeia was pretty much 'it' (in addition to the commentary volumes). So I selected a couple of Semeia to purchase. That's when I noticed by accident that 91 issues cost the same as 2 issues (a little more)!! And .... all in Libronix format too!!!

So if you're a rabbit-trail person, some of these journals can be picked up for a song (or rabbit food depending).
