We only have B&N in my area, but I do go to Borders when I visit my bro in Tucson. Betweenthe B&N I'm used to, and that Borders, I def choose Borders. Its not even that they have a bigger selection of books, but they have more things that our B&N don't offer...like movies and little odds and ends (journals, and scrapbooking things).
I want a Borders in our area
We also have a place here where you can buy used books and sell yours, but it gets really packed on weekends, and sometimes their selection isn't what I like/prefer.
