Wedding Favor Ideas-Budget $5 total

My goal is to find a favor that folks will find useful and won't throw away after the event. I'd prefer to stay away from edible favors and candles (I love them but so many folks are using the idea that I'd like to come up with something else).

My budget is $5/$6 each inc wrapping but I'd go less and wrap it myself. I went to the Mikasa outlet store in Tanger but the prices were the same as my local favor store and through the Mikasa web page. Our wedding is in Mar 2000

Any & all suggestions are welcomed! : )
