Report: Google offered $5.3B for daily deal site Groupon

Hot off the heels of an oft-criticized $700 million acquisition of flight-data provider ITA, search giant Google might now end up purchasing daily-deal provider Groupon for $5.3 billion, according to a report by AllThingsD. That comes just after reports of a buyout of the site for a mere $2.5 billion — less than half of what the latest reports indicate.
