The Washington Post has noticed that you can now find Google Offers on Google Maps. Google Offers seems to be Google's answer to Groupon.
Google presumably is working on a dedicated site for Google Offers and will have an official launch at some stage. However, if you can't wait, you can find special offers now by adding a Google Offers gadget to your iGoogle page.
The gadget lets you search a location for offers. You can also search for offers by a type, e.g. 'pizza', 'hotels' etc.
