[2]  Rent A Spot

U-Haul sometimes rents spaces where you can have packages sent and 
signed for.  End your space when the package arrives.

   [3]  People's houses

Find someone you do not know, and have the package sent there.  
Call ahead saying that "I called the store and they sent the 
package to the wrong address.  It was already sent, but can you 
keep it there for me?"  This is a very reliable way if you keep
calm when talking to the people.

Do NOT try post office boxes.  Most of the time, UPS will not 
deliver to a post office box, and many people have been caught in 
the past attempting to use a post office box.  Also, when you have 
determined a drop site, keep an eye on it for suspicious 
characters and cars that have not been there before.
