They have been registered in France too.
It is surely in relation with the coupons in Google Maps.

Maybe they'll highlight sites that offer coupons in Froogle or even in Google Search.

Wonder if there's any relation to the Google Kiosk patent:

The patent also mentions coupons...

It's been possible to create coupons using Google Local Business Center for a while now. Maybe they're just going to start listing all those coupons in a directory or something...?

They'll just bring Google Coupons back to life, right ?

Don't they also let you have coupon codes in Google checkout for sellers? I'm not sure if there are actual coupons though
