Although Amazon has one of the best prices on Confessions of a Shopaholic ($0.89), by Sophie Kinsella, the rest of the series there (and most places) is over $6 per volume. However, if you don't mind not reading on the Kindle, you can pick up the rest of the series, other than the upcoming Mini Shopaholic ($9.99), for under a dollar apiece at Fictionwise. They don't have the first in the series, but have books 2-5 in the series at 99 cents each (84 cents for members), as well as four additional stand-alone novels at the same price. Use coupon code eleven2010fw for an additional 11% off (it's working right this minute, but could stop at any time), bringing the member price down to 75 cents apiece.
