Lol, what decade was that?
The decade was the 2010s. I got a lot of stuff cheap back then from Amazon, mainly the IronMan books came from Amazon, and other stuff including $8 for the 1991 WBF Championship on VHS (Yes, I still have a VCR).
Gas was $5:03 USD per gallon here two days ago. It has since dropped to $4.70 USD per gallon, which is about where it's tolerable to me, but way above the tolerable range for many others.

$1 for a book is very cheap. Was that a promotion?
Nope. I was visiting my older kids when they were in college. We went to a bookstore (McKay Books) to find some books for their classes. That's where I found the Weider books on clearance. Joe Weider's Ultimate Bodybuilding was $1.50; so was Bodybuilding: The Weider Approach.
Here is a book I bought about 30 years ago and a vhs tape I have nothing to play it on
Hit Goodwill (or some other thrift store); you can get a VCR for $5. That's how I got to watch the 1991 WBF championship, my old Lee Haney's Mass Fuel kit tape, and all the episodes of "American Muscle" that I recorded back the 90s when I was in college (or, at least, home for Christmas and summer break).
