In August of 2006, Google announced that they would offer coupons for local business listings in Google Maps. They partnered with ValPak to get access to as many coupons as it could. Well today, Google has partnered with PennySaverUSA.com. If you live in the US, you will recognize PennySaver immediately. Its the coupons you get in your mailbox every single week that come with a mini classifieds booklet. This deal should add a lot more coupon data for the US market.

Are there any other countries where coupons display in Google Maps?
