To those who bought groupon,
If you think you have been scammed by Groupon. Simple. Go online or call your State Attorney General. File a complaint. It is easier than you fear it would be.
Groupon settled with various State Attorney Generals' or are under investigations precisely for many of the complaints I read here.
Here is the California AG's site. oag.ca.gov
If groupon claims they done nothing wrong then they got nothing to fear from increase scrutiny.
