I don't think most people buy the higher memory models but regardless don't really think fair to compare to make a point on the $1800 price point. $1800 is the lowest entry price for the Fold and should compare to the lowest price point for the N20U.
I've never paid full price on these phones and never will. And I think most people are like that in unless there is a promotion involved you won't get many people buying these at full price and Samsung knows it. That's why they offer crazy trade-in promotions to get people to get the new phones. I guess now with the Fold 3 they let you trade-in multiple phones now because the prices are just getting up there??
I've been lucky to have different options. I used my companies Verizon account to buy my Note 8 using a line upgrade for $450. AT&T offered the $1000 credit and my 3 year old Note 8 to get the N20U for $300. Right now a N20U on our corporate account if I use an upgrade costs me $649.99 and the Fold3 is $1200.
I already told my boss today... if Samsung comes out with the Note22U, I'm selling my N20U on Swappa and using an upgrade for $649.99 for wash.
