I work for a small business that was taking Dealfind and Teambuy coupons, but they never paid us. They filed for bankruptcy and changed their name to nCrowd.
If you are a merchant beware--you may never receive any money from them. Others who had vouchers who had not printed them simply had them disappear.
Not sure how a company can file bankruptcy and just open an identical company? This is major fraud and these people should be in prison!
