Luckily we can put stuff outside so I just leave what I need to sell outside of nook's cranny and sell it the next day.
The odd thing about this feature is it feel like a downgrade getting the baby nooks out of the tent because I recall being able to sell to them late at night even when the store would usually be closed, I hope at some point in the update cycle we might see a better option than the drop off box or a way to maybe make them stay open till like midnight?
other than the dropbox that nook’s cranny has, currently there’s no way to sell things at night. i’m hoping that maybe ordinances will be added in a future update so that maybe the ‘night-owl’ ordinance can be in effect again for those who play at night
