Both B&H and Adorama list the Nikon MB-D16 Multi Battery Power Pack on sale for $136.95 (regular price is $336.95). According to Adorama's listing, the price expires today, August 29, 2021. B&H is sold out of theirs so not sure if it can still be purchased at that price.
Considering the D780 is already being sold, perhaps Nikon won't be making this grip for long.
