My experience with Book Depository, initially lost a lot of books when I set my delivery address to my home. One set of books even got delivered to the wrong address and the person was kind enough to drop it off at my place. I suspect this was just Pos Malaysia being irresponsible.

After that experience (and multiple refunds) I switched to Kinokuniya.

A few years back I started using Book Depository again when one of my colleagues advised to set the delivery address to the office, which in his opinion would lessen the chances of the books going missing. Since then, I only had one order go missing out of around 20 plus deliveries, and the missing order was delivered successfully the second time around.
