Is it really so hard to pack a book well...

I received four books just now from four different dealers. All were wrapped in paper (one in plastic), one was then wrapped in bubble-wrap and packed well in a box. The other three were in envelopes (two padded, one plain). The least expensive was $75. 3 of 4 dealers were "established" dealers. I just don't get it.

I guess I understand packing a reading copy with a minimal amount care/effort, but when a book is worth a reasonable amount, it is just unacceptable (can you tell that 2 of the 4 poorly packed volumes were damaged as a result).

I guess I understand a bit better why we get so many "I can't believe how nicely packed my book was..." emails from people
