Much of the time, we will be able to accommodate this kind of extreme-rush turnaround, as long as the order is placed before noon on the day it needs to be shipped. There will be times and circumstances, however, when this is not possible. This varies on a case-by-case basis, so you will want to give us a call before placing your order.
Please note that, without a verbal or written guarantee, we do not guarantee same day turnaround. Our standard turnaround guarantee is three business days, and rush turnaround (included with express shipping services) is two business days, though we generally get things shipped out much more quickly.
Also, in order to get an overnight guarantee, the UPS Next Day shipping service must be chosen as your shipping method.
