...without leaving your computer:
--check Facebook for their fanpage. Become a fan.
--give them a good review on Yelp.com.
--comment on their blog. If they know what kinds of customers are reading, they can tailor their writing to those customers.
--send an email telling them how much you appreciate them and why.
--sign up for Indiebound.org. Find the bookstore and become a fan.
--mention on your blog, Twitter, email update, Facebook status, etc. when you've had a good experience there.
--instead of ordering a book on Amazon, send them an email and have them order it instead.
Did I miss anything? Leave me a comment if you can think of other ways to support a local bookstore without getting out of your chair.
