To be relatively certain your item will ship "same day" with Next-Day as your expedited shipping method, it will depend on TIME OF DAY you place your order. Our centralized order processing staff work on Eastern Standard Time (EST) and all expedited order placed prior to 12pm EST will be processed and ship that day and will be delivered the next day via UPS normally. Of course, there are exceptions due to availability, shipping "out of area" maps, and our Monday through Friday shipping schedule. UPS does not deliever on weekends.
An order placed on Friday night for example, with Next Day Air service, will not arrive until Tuesday, as it cannot be picked up until Monday.
