If you lived in my town you could buy a Preferred Reader card from the local bookstore for $10.00 per year.
I also have a Barnes & Noble card. B & N sends out email coupons often.
I got my B & N card because I got tired of having to pay for my books in advance when I did a special order at the local bookstore. I normally pick up 3 or 4 books at a time and I much prefer to do one check instead of many checks. I'm sure that the bookstore has felt the loss of my business. I've had a B & N card for several months now.
I understand that Borders has a card, but I haven't looked into getting one.
I got my B & N card when I couldn't get the newest cookbook of a junior league from the local bookstore. As I recall, Borders didn't have it. B & N had it and I bought the card then.
Back when I had a BAM card it cost $5.00 a year.
