Samsung is offering Flip 3 256 GB unlocked for $555 after instant discount and $195 Education offer with no trade-in
Samsung Watch 4 40mm is free
If you trade in Samsung S21 Ultra, the trade in value is $625 - so compared to the trade-in for Samsung S22 Ultra, the trade in values are not that great.
However, if you trade in apple phones (trade in values are not good either but there are some combination that might work well), Samsung throws in a "Galaxy Bud Pro" for free.
Apple combination that I tried:
IPhone 11 : $300 trade in with Free "Galaxy Watch 4" & "Galaxy bud pro" for $332.50
IPhone 12 : $420 trade in with Free "Galaxy Watch 4" & "Galaxy bud pro" for $243.83
Hope someone benefits from this deal
