J&T also the same.
If delivery area is high population density area such as condo/apartment, it's possible to delivery many packages in one day.
One guy use a pickup truck, another guy used Alza.
Every time come, sure got a few other packages for my block, in addition to mine. My place 5 block, one block 3-4 packages , and surrounding area another 5 more condos.
They can potentially deliver 100 packages during peak sale period
