It sounds like it is shopping addiction type behaviour.
I once got a book on British regional cookery that described the food, rather than actually providing a recipe.
This and the sample text sounds like a book which was both dreamt up and written entirely by AI and then self-published. Unlike traditional printing runs, amazon print the books individually as they are sold, so you could in theory come up with 1000 variations on a book and market them all individually to each niche category without ending up with hundreds of redundant copies.
DS2 is age 7 and really interested in trains, so I got recommended a bizarre book like this once. It looked like AI so I clicked it out of curiosity and rather than being "101 train facts for 7 year olds" as the title said, the reviews were full of disappointed people saying that the facts didn't really make sense, the text was babyish and the book inside looked like it was aimed at toddlers, and worst of all the numbering system turned to complete gibberish part way through the book!
God knows who is setting up the instructions to churn out this garbage and market it to unsuspecting people! It's like those t-shirts that get auto generated so you are tricked into thinking "Wow, that shirt looks like it was designed just for me!!" it WAS, it's using your data.
But someone with a shopping addiction is probably even more likely than the average person to be taken in by something like this. And perhaps less likely to actually check the product before passing it on to the intended recipient, as well.
