I need help... I have been on the phone with newegg, XFX, and AMD. Where do I send this rebate in. I registered my r9 280x on xfxforce.com and I followed neweggs instructions on printing the papers out getting the UPC... etc. Now where do I mail that in?? There is no instruction?! I have an envelope with the papers in it ready to send, I applied for the rebate already online but I am pretty sure they need these papers... Help me please asap
