There's another value that's lost, more human, of just browsing a charming book store.
My brother's store is slowly folding, largely due specifically to Amazon selling cheaper than he can purchase wholesale.
Unfortunately that battle is with our banking system, and until its won you will continue to see the proliferation of companies engaging in this behavior. That said, amazon will eventually be the dinosaur that walmart has become, and its very obvious from a ground level prespective that we dont have the right foundation for the infinite scale we seem to desire; too many "leadership principles", too much reworking of company policy, too much switching us from database to database.
(Let alone the Amazon shoppers who waste their time demoing and trying products in store, then act like they've caught some scammer if it's a few dollars more than online.)
