It will Suck big time, at first. UPS stands to gain more volume, buy businesses offering Saturday delivery without the extra super high surcharge. Some programs when ordering online, didn't even offer UPS if the scheduled delivery date was a Saturday. This option over time should move to the top. Business / Corp accounts can be picked up on Saturday if they want for $9 (here anyway). This should catch on. I am part time, so my day Has packages from online orders that just sit on the dock till Monday. Some are Air... Quicker delivery.
Con for our building, is we can not even hire enough PT people to staff the normal work week...
