Bmv is NOT the place to go if you have a specific book in mind. It keeps cost down by not keeping a digital database and it is too huge to operate like an old school bookstore where the owner knows every single book.
Instead it is like a well organized library with quality selection and inexpensive prices. Only complaint, it seems that the science section has been dumbed down by all the new age science books but they still accept used books I believe.
It is always fun to spend time in this bookstore and I spent a fortune here. I hope time would not degenerate this store.
