Amazon has the following book on sale:
Extremely unlikely, but this isn't the right forum to ask.
Simple ebooks in the Vyrso now Faithlife-E-Books sometimes get the same sales prices that you see in other places... However anything in Logos is considered value added and has been tagged (even if no tags are there) and do no qualify for ebook sale prices since they are a value added book. That is simple FL policy.

Interesting. When I bought that book in 2012 it was a Vyrso edition. It was $7.49 back then and I'm not sure when or why it became a Logos edition. It also had a different catalogue listing https://www.logos.com/product/19517/
