Google's $6 billion bid for Groupon didn't work out , but it wasting no time preparing its own competing Google Offers local advertising product. The first hints of Google Offers came out last week. Google confirmed it, calling it a "test of a pre-paid offers/vouchers program," but offered no further details. Well, we have further details, courtesy of Google's very own search engine. (When PR fails, just Google it). There is a very simple way to get a list of active Google Offers coupons. It is kind of a back door, but if you do a search for "coupons site:maps.google.com intitle:Google Offers," you can see almost 42,000 results, most of which link to individual active coupons. For example, here is one for a free yoga class in Chicago (Groupon's home turf) or another one for 50 percent off lunch at a vegetarian restaurant in Watertown, Massachusetts. You can also add an Offers gadget to your iGoogle home page which shows offers near you.
