Definitely. Question though what was he charging on shipping, cheap shipping usually means cheap packaging. Except of course for a few sellers.
Irrelevant. Poor packing as described above is fully sellers fault. Doesn't matter what the charge is, I could list a book with free shipping, that doesn't mean I am going to put a stamp on the slab and hope it makes it there, or put it in a box and drop it in the ocean. You would think someone here wouldn't ship a slab in a bubble mailer...on other sites can't be too sure though.
