That sucks. At least he gave you some money back. I had a title belt I bought privately and when I got it, it was a total POS. Sent it to a guy to get all the rivets replaced for $75, then sold it on E-bay for about half what I paid for it. The guy took it out of the box and most of the rivets had broken and the majority of the plates had come off. PayPal and E-bay made us split return shipping, but he got the majority of his money back.
Re-attached all the plates with Chicago screws myself and sold it again for even less than the first time. That belt cost me a lot of money to sell, lol. Sorry, don't know what this had to do with the book you bought.
They can. I picked 2 books today from a 6 book set, and I already have the last 3 books. Now, I HAVE to get book 1 from a private seller on Amazon because it is OOP. So, I'm not really looking forward to that.
