Hey guys, I know this may sound like a stupid question but does UPS operate on the weekends? I'm waiting for some stuff I bought on the internet to arrive through UPS. I know that at least one of the things has to get to the "regional center" before I can get a tracking number for it so I'm wondering if I don't get that number tommorow if it'll end up getting emailed to me over the weekend because my package arrived at the "regional center" over the weekend. I'm also trying to figure out if I'll need to be here over the weekend to sign for my other shipments.
