A2: Groupon

The Chicago Tribune reports on survey results by Ann Arbor-based ForeSee Results, which asked online shoppers about their use of Groupon and other “deal” sites. According to the report, the ForeSee ”found that while usage among deal sites like Chicago-based Groupon and Living Social is strong, it is less clear how much new business their deep-discount coupons are driving to their clients.” [Source]
