Recently when I buy books on Amazon, they're often cheap versions printed in India. Sometimes there's even a "Only for sale in the Indian subcontinent" label on it. The quality is much worse - flimsy paper, faded ink, rough edges, and often quite dirty despite being new. Does anyone know of a more reliable place to buy new books?

bookshop.org proxies local bookstores. Chances are if you’ve visited a physical bookstore you like they’re selling on there.

I've been using alibris.com

Better world books is better. Try them in the future. You can even get really good used copy for much less on most books.
