Check the price of Turnips with Timmy and Tommy at Nook’s Cranny daily. the prices definitely change once each day , when the shop opens, but in past games they have also shifted somewhat within the day, at midday. an important note is that Turnips must be sold before hour on Saturday: you can’t put Turnips into the drop-off box. they're going to only be sold when the shop is actively open.
