Please ignore my post #788. It's just about worthless.
For a period of approximately one month, October 2018, the book A History of Biblical Interpretation, Vol. 1: The Medieval though the Reformation Periods Alan J. Hauser & Duane F. Watson (editors)dropped in price to the range of $3.19 - $3.99. Checking my Amazon account, I saw that I had purchased it that month for $3.99.
Honestly, I'm not gloating. If I didn't post it during that time, I'm going to feel like I failed in doing my job.
I'm going to go back and check my posts in October 2018. I hope that I or someone else had posted it.
The price had held fairly steady around the $40 mark, until at least January of 2017. There is a way to go back further than that, but I haven't ever figured out how to do it.
Those who didn't get the deal might consider having
ereaderiq.com (the site from whom I got most of facts above came from them) them do a price track--they'll notify you when the price is the same or lower than the price that you tell them.
