I am returning a DOA motherboard to newegg. I requested a RMA number and an email came through. I printed the document and did everything it said to do. It mentioned an unscathed upc code. It gives me two codes on the paper but I am wondering. Does it mean I need to ship it back in the original cardboard box it came in with that upc code? Or just use the one newegg gave to me? Any help is appreciated.
