A method and system for efficient package delivery in bulk to pickup locations for recipients in which items ordered by different customers from one or more different retailers, suppliers, manufacturers, and the like can be sorted within and picked from an on-hand inventory at a distribution center and packed into a package for delivery to a specific pickup location for a specific recipient. A replenishment order for items to replace the on-hand inventory at the distribution center can be made to a fulfillment location to maintain inventory levels defined for an item at a distribution center. The items to replenish the on-hand inventory at the distribution center can be shipped in bulk from a fulfillment location in containers organized by item identifier. The items can be sorted at a different distribution center, still organized within containers of all the same item identifier, to reach the distribution center placing the replenishment order for the items.
