Surprised? Australia groupon is the first one. Cudo below to NINEMSN and they almost have commercial on TV everyday but the result is not that good. Maybe the main target market for group buy website is young people, they just don’t watch TV. Spreets belong to Yahoo7 they are quite good.

How about rest of group buy website?

Obviously these web sites far from the top 4.If you really want use group buy website, I think you can forget these website.   My personal bad experience on Spreets tell me just be careful on group buy website. Actually Have a look of this article from The Age you will know I’m not the only one who not happy about group buy.
