amazon 4-star

The Amazon shop feels illogical. 4 or more items in a row are related as high.
But it makes sense.
For example, if you go into the right book shop and find a collection of photos you like, you will be "buying it from Amazon because it’s heavy”.
Even if I choose a valuable book at a great price, although that bookstore will make no profit,
I’ll end up buying the 'amazon 4-star' item on Amazon even if I don’t buy at the store in the end.

It's unbelievably crowded. And kind of fun.
I reminded me of 'King's Idea', but you don’t see them anymore.
