Penguin incorporates shipping into the wholesale price, effectively making shipping free.
However, floppies will most likely be available in most regular book stores now too. Anybody who already carries an account with Penguin will be able to sell floppies. Kinda like a new newsstand. That may draw some business away from the LCS, but, it may give more exposure for the books to other age groups. I wonder if this comes to fruition, if they will have different ‘editions’ for the Barnes and Noble type stores.
