From Danielle Bean's blog:

And finally, a shopping tip: Amazon is getting into the grocery business-- with free shipping on all orders of $25 or more. And they have a promotion going where you can get $10 off an order of $49 or more between now and August 31. Even if you just stock up on shampoo, diapers or wipes this way, it seems
worthwhile to me. And the bonus is, no trekking through Sam's Club or BJ's with a cartful of whiny kids begging for ginormous packages of Keebler cookies. Go here for details.
