probably depends on where you live in comparison to where they are located- how long it will take- and if they use the USPS or UPS- or a different shipping method.
check their shipping policies- it probably tells you to expect your order in....some length of time- or call their customer service # and ask- they can probably tell you pretty close.
when i order on line normally i receive an email confirming the order was recieved- then with in a couple days i receive an email telling me it has shipped- the method- tracking #'s- and when to expect it.
