Ok, so I just signed up for this now, so I haven't really tested it, seems nice though. Installed it on my Android device with no issues.
You don't have to have a smartphone, looks like you can just use it on the website, but the smartphone allows you to keep your list with you. The website has a great, intuitive, layout and adding stores is a breeze. It asks your food preferences then finds you deals at your stores. Pretty handy looking so far :)
