A few weeks ago, Kristen Faughnan got something that surprised her: a “low balance” text message from her bank. That didn’t make sense. She’d just paid for a haircut, but she knew how much was in her account. Even after paying her stylist, it was much more than the level at which the bank would tell her she was almost out of funds.
“I logged onto my bank account to find two recent charges from Groupon,” she says. They were from a cologne store in Texas. Faughnan lives in Pennsylvania.
