Jane,
You might try Amazon on the web. They are generally pretty cheap on new CDs and if you were to order another CD or something else you wanted that puts the total over $25 shipping is often free on their "super saver" option.
I bought You and Me from Amazon as an import over a month prior to release in the states and the price was very good for an import. I am hoping to have Joe autograph it for me when he is here is Vegas next week.
Tower Records used to have good pricing, but that has changed recently and I have found Amazon to be the best deal most of the time.
Nothin' but the Blues
