Amazon Prime is a genius program, and I think Amazon Tote has the potential to be as well. Free weekly deliveries of anything you order is perfect for most folks, who probably go to the store once a week to stock up.
I had never heard of Amazon Tote, so you piqued my interest. In case anyone reading this is similarly interested, it looks like a KILLER concept when they roll it out (http://tote.amazon.com/AmazonToteLearnMore) BUT currently it's only for zip codes 98112 and 98040.
Yeah, I hope that gets rolled out more widely. I love buying stuff from Amazon, but do feel a little guilty about all the packaging.
