A problem with Logos pricing?

I have heard many people say that Logos offers a great bundled deal for getting commentaries and books. 

I recently decided to do some cost comparisons to see if this was the case and I noticed something interesting. Logos does not compare it's digital prices with other retailers digital prices for books, they actually compare to print books.

This is very strange because when you buy Logos you are not buying any print books at all, and buying individual digital copies of the books they offer are available all over the place, whether it be Amazon, or other Bible Software like Olive Tree.

Illustration 1: The Pillar New Testament Commentary Series on Logos. It is advertised as being $524.95, and then puts a print comparison below saying $715. This seems like you're saving money...

What they don't show you is what others charge for the Digital editions on an individual basis. I took Carson's commentary on John as a comparison. This was not on a special sale at all (although Amazon always marks all of it's items as cheaper than some other price). And the individual unit price was $31.56.

So here's the math:

15 Digital Kindle Copies (at $32 average) = $480
15 Digital Logos Edition = $524.95


Here's the bottom line then:
You actually aren't saving any money at all with Logos, it actually costs more..! Even though it's bundled which is usually a cost-saving benefit, Logos actually ends up costing $44.95 more than getting digital editions elsewhere, rather than the $190 savings they claim you get.

What is even more interesting is that there are often sales through other digital retailers that make Logos look even more expensive. Recently Olive tree offered this same 15 Bundle set for only $150. That made the Logos Edition over $370 more than the Olive Tree Bundle while both were at Sale pricing.

Comparing digital prices with print prices is not the most honest way to display your product. Admittedly Logos does acknowledge the original price is print in very small font, but there's no need to make this unhelpful comparison when a plethora of other retailers sell digital just like them.
Overall, be warned, Logos doesn't actually save you money on a lot of the items they offer. But most people won't notice as the bundles they purchase include such a huge amount of books that comparisons become complicated.
