A Cool App for Wedding Couples on the Go

I came across an app for the iPhone that I wish I had when I was planning my wedding.  It's a barcode scanner from MyRegistry that allows you to scan items when you are out and about using the camera on your iPhone!  The item is then added to your wedding registry.  Then, using your phone you can track and monitor which items have been purchased.  It also lets you know if the item you scanned can be found cheaper at a different store.  Pretty clever!
