Book Buying Habits

I've been thinking about my book buying habits. When I was young I'd order them through Scholastic Scope. Then when B. Dalton opened in the west coast, I made dad take me there every Friday after school. I suffered a lot when B. Dalton closed its doors, and for a while I depended on the wonderful members of the romance community - RRA-L - to get me the books. Then Amazon.com came along and The BookShop opened, so I had two sources to buy books. I mostly bought them through the book store. However, since the book store didn't bring all the books I liked, I'd ordered those through Amazon.com. About 3 years ago, I started ordering books from BN.com when I got their Mastercard and saved in the process. After the BookShop closed, BN.com became a lifesaver, especially since they have the free S&H after an order of $25. Now Borders opened here about 10 months ago. Although mostly I keep ordering books through BN.com, now that Borders sends me discount coupons, I sometimes buy a book there. A few months ago, I also bought a PC Pocket, so I've been downloading free books through the Guttenberg Project. I've bought a few ebooks directly from epublishers. However, my collection of paperbacks is still bigger than my ebook. *lol* How do you buy your books?
