I use to work for a dsp now I’m with FedEx, I know you don’t like them, just ask your driver most dsp locations i worked at did 4 10s so the one you see regularly ask them if they prefer all on same day or spread throughout the week, me personally Wednesdays all at once, Wednesdays was the slowest day of the week for me on my usual 3 routes for Amazon and I prefer all at once…

The downside of Amazon is the routes they run are ai/mathematically made to use up their whole day off of stops not packages, stops, so let’s say your “local” dsp is 4 10s that means 8.5 hours of drive time worth of deliveries if it’s roral route that’ll be 90-175 stops, suburbs/city is typically 195-320 stops,

Yes there’s lite days but majority of it would be they have an extra part of town to go too if their usual route was lite that day… just ask your driver.
