My friend packed up her apartment and called me up.  Do you need napkins?  Dish towels?  Tea?  Bungee cords?  Worchestire sauce?  A can opener?  Well, sure.  I know that the city recycles itself in a lot of ways, and I can't imagine every bag gets opened up and inspected for useful/intact things.  I couldn't carry everything, and it pained me to see perfectly good things go in the trash...to think, this happens every day!  (But don't call me up if you're moving to LA/London/Toronto - my little place can't take too much more...)
