Samsung just started a trade-in promotion on December 10, good until December 23, 2017.
If you buy a select HDTV directly from Samsung.com, the will give you an instant credit of $200 if you are trading in an old Sony or LG TV, or a $100 credit for any other brand.
These are the only models on which the credit can be used: UN75MU6300FXZA, UN65MU6300FXZA, UN55MU6300FXZA, UN65MU6500FXZA, UN55MU6500FXZA, UN65MU7000FXZA, UN55MU7000FXZA, UN65MU7500FXZA and UN55MU7500FXZA
So for example, the UN55MU6300 (a 55-incher) which most stores had for about $599 on Black Friday, is still that price at Samsung.com, and with the instant trade-in credit, it will only cost $399. Shipping is free.
