UPS, Delivery that is

I ordered New processor and GFX card upgrades for my computer. They would have been at my house today but nobody was there to sign so UPS took the package back! They will try again tomorrow, that doesnt do me any good i will still be at work!

Is their a way to recieve without having to sign?

And, were do they take your package to? I checked the tracking number, it just gives me the city.

This is frustrating
