The discount applies to both Galaxy Note 20 and Note 20 Ultra, unlocked. It also applies to all the colour variants of the phone; Mystic Bronze, Mystic Black, Mystic Gray, and Mystic Green. The price cut is available from Amazon, B&H and BestBuy.
Some people believe that the price cut is an effort to push out more Galaxy units before the announcement of the iPhone 12 series. It is unknown how long will the promotion last.
