Drop off delivery means that the shipper will bring the package to your address, pull the truck up to the front of your house, load the package(s) onto the lift gate on the back of the truck, lower the lift, and push the package(s) onto the sidewalk in front of your house. If there is not an incline or stairs leading to your house, they may wheel the package(s) to your door. But, the point of drop off delivery is that the package(s) are too heavy for one delivery person to haul up an incline or upstairs, and it will be your responsibility to bring the item inside. It is also your responsibility to unpack the item, completing any necessary assembly, remove the debris.
