If your hub is open on Saturday, you should be able to go get it with no problem. Once your tracking number becomes active tonight, you can call the 800 # and tell them to hold at hub for pick-up and they will relay the message and you won't have any problems getting it tomorrow, as long as your hub is open, some are not on Saturday...YOu can look yours up by zip code on the Fed ex website. Hope this helps! I have done this!
