It appears most of the local deals offers are coming from Google lately. Groupon appears second, while LivingSocial is either a distinct 3rd or non-existent.
1) Google is undercutting Groupon's charges on small merchants. Goog has deep pockets.
2) Google sees Offers in bringing more traffic to Goog in general. Ads make more $. Goog has side products [search, maps, youtube, gmail]. Groupon does *not.
3) Amzn is *not encouraging LS bc there's not as much synergy on that 2 businesses: if customers spend $ on local deals, less on amzn. [for Goog, local deals may take away current $ from wallet, but ads may benefit later phase and it's just ideas - advertisers must ascertain that Offers takes away spending power with the increased traffic]
