I think the delivery people are assigned by Instacart so no two stores on the same delivery at this time. My first delivery extra charges were delivery charge, service charge, and tip. The second order on the same day from a different store, delivery was free, but the other two still stood. I chose the percentage of tip and I also tipped at the door. In Las Vegas everybody expects tips because so many people live off tips.
