I'm going to buy the Samsung 85" QLED 4 K 80 series TV for my Man Cave at Best Buy before Thanksgiving at the latest and I started looking seriously at prices around Labor Day and noticed this past week that it has dropped by $300 and it wasn't a sale price drop. My questions are:

1) Is there a chance it will drop even more by November or worse will it go back up that $300? I don't know how the big priced things vary in price so much there because I'm usually not buying them lol. But if it might go back up I want to jump on it this week AND since it's one of the newer and better versions, I don't think it will go down any more in price at all for a while or be on sale closer to Black Friday. Is that accurate?

2) Should I get the Best Buy service plan with these huge tvs or just do the warranty that comes with it?

3) Know of anywhere else that offers it even cheaper?

I'm hoping someone in the know with Best Buy is on here and can answer these lol.

Thanks guys!
