Dear Amazon,
When I’m buying a book from you, why not take your section called “Customers who bought this item also bought”… and filter out the stuff I’ve already purchased? I mean, cool, it’s nice to see that other people have similar tastes, but I’d rather see books I don’t already own.
As someone who can and does read 4 books in a day, having only 100 items returned means there’s a high chance I’ve read a large number them.
