RiverGirl.... http://www.amazon.com/gp/product/B0015T963C/?tag=cancuncare-20 This was on the front page of Amazon's site just now.. $259 with free US shipping.... says on the bottom; "When traveling abroad, you can download books wirelessly from the Kindle Store or your Archived Items. U.S. customers will be charged a fee of $1.99 for international downloads. " So.. I'm wondering if you'll get charged $1.99 every time your kindle hops online to get the newspaper in the morning....
edit... found this about Mexico... So I guess you'll want to register as a "non-U.S. customer" to avoid extra charges....
