U8000F in 43" ($374.50), 75" and 85" is half price on the gov store. The rest of the sizes aren't as good a discount. I can't find many details around these TVs, just reviews of what look like predecessor models.
U8500F 85" is also $1249.50 (50% off). Unsure what the difference is, the samsung comparison feature says the only difference between the 8000 and the 8500 is the stand colour (Black vs Titan Gray lol).
EDIT: My post was edited to say governement store but I'm getting this through our corporate portal via rewards gateway (this past deal has a way to gain access https://www.ozbargain.com.au/node/891130)
These products cannot be delivered to a number of postcodes in NSW, QLD, VIC and WA (as well as all of TAS and NT).
Literally just bought the 43 inch two days ago for almost twice the price :-p I like it so far, it's a steal for this price
Edit: as I literally have the bought still right in front of me, I can see that mine says 8500F so unsure if there is any difference. Either way seems like a great price.
