Sunday only, today's Fry's ad has a no-name 75" 4k tv for $999 with promo code. When you drill down into the ad it shows two different TVs, one a "Atyme", one a "Silo":
I'm sure these are pretty horrible quality being no-name brands, but definitely the cheapest I've ever seen a 75" 4k going for.
If anybody wants to take a chance and needs a promo code, PM me and you can have mine. First come first server.
