I bought a $550 iphone on groupon and turns out my Tmobile rep checked it and said it was either stolen or a broken contract and had a bad IMEI number, either way there was a permanent block on it and should be returned. Since then I have sent it back and its been over 10 days and still no refund, so I am out the money and no phone. I believe Groupon could be sued or the seller for shipping stolen goods across state lines, someone should have checked the IMEI number before shipping it, seems after some research this is not an uncommon problem, yikes! I will never buy on Groupon again.
