Google alledgedly attempted to buy out Groupon for $6 billion in 2010 but ultimately decided to start going its own service.
Google Offers made its debut in April of this year in Portland, OR, and has since expanded to 42 metro cities. And starting this week, you can get Google's offer straight on your HTC EVO (or any Android device running Eclair or higher).
Assuming you're in one of the supported areas, this is how the app works: every day, Google Offers lets you know about some location-based deals of the day. If you want the deal, you buy it. Some of them are offered in limited quantities, so you need to act fast. The deals are usually around 50% off the normal price and generally pretty good.
One of Portland's deals today, for example, was for a fancy $8 European-style sandwich for just $4. Hell, that's cheaper than Subway!
