I have some great used bookstores near me that I can browse on a lunch break and have established a decent relationship with the store owners. I love to have a physical book and the interactions with a store owner that lives and breathes books can't be overrated, they always have a suggestion for me based on current interests.

I do own an e-reader though and will occasionally buy books that I just can't get in print, I've been really into the Warhammer 40k universe lately and while I could find them used on ebay they are generally pretty pricey. I did score two collections at my local thrift store last week though for $3 a piece and was pretty happy about that.
