I've often wondered the same thing myself. I once had three packages from EF waiting for me after I got back from Spring Break. I was happy as a lark, of course, but that's a lot of boxes! I think, from the order confirmation/order sent emails, that the orders are just in one big queue and get sent out for fulfillment in the order they came in. Maybe it's done this way to ensure the fastest shipping possible? It would be pretty cool, however, if all orders directed to the same person, same address that are made every 24 hours could be shipped together.
