Not sure how far the local FedEx center is for you but if they try to deliver it, you can pick it up, I think... you can with UPS but only once they try to deliver it.
If for some reason they try to deliver it after everyone in the office is gone, then it would be at the local FedEx place near my office. Which is about 40 minutes from my house. I don't think i'll make the drive on a Saturday unless I find some free time (Which is hard to come by with a 2 year old).
