You don't say.
I buy books from Amazon or local bookstores (old & new)...
never have I returned a book. Maybe its me but I don't treat books like I would do for something like a slow cooker, laptop, office chair, calculator, Ninja professional juicer or camping equipement.
I mention the latter above because those were items I've returned (not the books) to Amazon in the past year due to a malfunction or something broken/damage.
By the way, I collect books and I'm one of those types of people that go to book signings in many different topics. Thus, I view books very
differently than anything else I purchase. Same for my other collections.
Heck, I still have my academic books from college although I'm sure those that failed the classes would say its
too difficult to understand while others excel in the classes.
This all reminds me of classes at the university...the distribution of grades were between A (excel), B, C, D & F (fail). Yet, some needed to pass the class because it fullfulled a critical requirement to move on to the next level. Those students would "re-take" the class and try again.
Interesting when talking to fellow students from the same class. Some would say it was easy, some would say it was hard, some say the instructor sucked, some say the instructor was great...some really didn't have much of an opinion...
So many different opinions from those that took the exact same class.
In some ways, traders do the same. Those that fail...they move on to something else. Those that succeed...a few will take the time to defend it or praise it.
