Does anyone know if Nikon offers labor sales on their lenses? I recently came back to Nikon have a Z7II (Z9 on order), the Z 14-24 2.8, and the Z 24-70 S. I keep debating back and forth between the Z 70-200 2.8 or the Z 100-400. I'm going to order one of them in the next week and then realized Labor Day is right around the corner, and perhaps there is a lens sale on the horizon.
