@switchingsocial While it's not supporting shops, if you're in the US, there are loads of libraries that have a vast selection of e- and audiobooks. I basically don't buy them at all anymore.
As for wanting to purchase, I stick to Barnes & Noble, who, while definitely not indie, have much better labor practices.
