Do I have to be at home for UPS to deliver my item?

I recently ordered something from amazon today and the shipping will take 4-14 buisness days(Free Super Saver Shipping). Do I have to be at home for the delivery? Or what will UPS do with my item?

Also, if UPS leaves my item by the front door and if someone steals it what do I do?
Its a video game. What can they do?

If the shipper requests 'Signature Required', the driver will leave a note on the door. You then have to option to be home at the time they make the next delivery attempt, or call to arrange alternate delivery instructions. In SOME cases, you can sign the note to authorize the driver to leave the package at th door on the next delivery attempt. I either have packages delivered to the office, or arrange to pick them up at the UPS office, which I pass on the way home anyway.

If the shipper did not request Signature Required', the driver CAN leave the package at the door, or in what they consider a 'secure' location. In my experience, that translates into being 100% visible on the front step.
