If you qualify for 8% eBay Cash promo, you can stack with the 20% off (max $50) to this eBay seller, vipoutlet.
Yes, it is refurbished, but they have a 90 day warranty, and a 30 day guarantee, so I'm willing to take a risk.
Yes, I know some people have indicated bad experiences with vipoutlet, but there have also been reports that they have no issues with their service.
Yes, I know it is LG, which some people have an issue with how their panels are RGBW. I understand that it may not be "true" 4K UHD in their eyes.
But for $527 for 65", I'm willing to take a shot at it. I saw one the other day in store and compared to the other TV's, I couldn't make out a big difference.
