Will UPS Deliver my Package Tomorrow?

I think you'll get it on Tuesday or even later. Even if the company had it boxed up and ready to go on standard shipments on Saturday UPS doesn't pick up shipments on Saturday. Monday would be the earliest day it would be picked up. The pick ups are in the afternoon, after the deliveries. This means they won't get it at off the truck until late Monday. It will be sorted and set up to be delivered Tuesday at the earliest.
