In over a decade of patronage, I cannot recall ever having a single successful conversation with a staff member (other than "These books, please.")
The bookstore receiving 50% of retail price for providing fungible copies of books, bitwise identical to those offered by all other bookstores, without even a scintilla of value-add, has struck me as something in urgent need of radical corrective capitalism.
By comparison, Amazon recommendations are routinely as good as my sister's, their customer service has been top-notch, their prices are cheaper, and the Kindle has transformed my experience with the medium and quintupled my consumption. I am in no danger of confusing Amazon with another shop that starts with A.
