dont assume they will, as simple as it might seem, there are hundreds and hundreds of orders going out, they will ship them as they get them, by item, or some system to make the shipper's life as easy as possible. email them and ask for your two orders to be shipped together, do it as soon as possible so they can make sure it gets done, and to make the shipper's, and anyone else involved in the shipping process/customer service contact as easy as possible and then youll be sure to get it shipped together
