Though Google has made offers a component of their Shopper app, today a standalone version was released to the Android Market. The app displays offers near your current or selected location and allows you to buy into deals directly via the interface. The app also provides visual receipt, so you should only need flash your phone at applicable businesses to redeem offers. Offers has been slowly expanding its footprint, recently becoming available in cities such as Baltimore and San Diego. Head over to the Android Market to download the new app.
