I attempted to purchase a refurbished laptop from groupon. They sent me several emails saying that the transaction didn't process and the purchase did not go thru. Based on this, i made other purchases. THREE DAYS after the attempted purchase, i checked my bank account to find that the charge HAD been put thru and that it was overdrafting my bank account. I spent another THREE DAYS trying to get my money back and my bank refusing to file a dispute over the charge! DO NOT BUY FROM GROUPON!
