How much is it to have the delivery company lower the chairs to the sidewalk for us?

On page 2 of the quotation there is a review of the shipping costs. We pack the chairs on pallets and therefore, if you need the trucking company to bring the chairs to street level, you may need a liftgate which is the mechanism that the truck will use to lower the pallet to the ground. The added cost would be: $58.00. Trucking companies charge ala carte for these extra services. If you need a delivery notification, the cost is +$28.00.
