On the Google Commerce blog, Google announced today the launch of Google Offers in 5 new markets: Charlotte, Kansas City, Milwaukee, San Antonio and Tampa.

Additionally, on Twitter, they announced launch in Columbus.

It’s now available in over 40 markets.

“2011 was quite a year for Google Offers. In only six months (since we first launched in Portland) we introduced amazing deals from beloved local business in 33 cities in the U.S., launched national deals and released our first mobile app.”

Expect Google Offers to continue to gain momentum as it expands into new markets. MerchantCircle put out survey results last month indicating that more businesses intend to use Google Offers than even Groupon in the future. Considering Google’s strategy of integrating its products with one another, this is hardly surprising.

Google says it plans to launch Offers in Oklahoma City and Omaha soon.
