I bought a 360 at costco in December of last year, it is still under warranty. I had the 360 flashed and was banned from xbox live. I bought another 360 off ebay, but it started to give the three red lights. I have the original box and recipt for the 360 I bought at costco. I'm going to try and return the ebay 360 to costco. The manufacture date on it is 2006-03-11 . Does anyone no if costco scans the back of the 360 or do they scan the box that the 360 came in? If they scan the 360 then I will just ship the 360 to MS with my receipt for a free repair., but was hoping they didint scan the back of the 360.
