If you're tough on shorts and pants like I am (rips, popped buttons, etc.), then this is a great tip. Instead of throwing out a torn pair of shorts, or shoving them into the back of the closet, get em' fixed.
There are still sewing shops out there, and even some grandmas willing to help. You can get most anything fixed, even the worst of rips.
I have shorts that are 10+ years old that have been brought back to life again by a seamstress at "The Stitchin' Post" on 23rd St.
For a few dollars you can save a lot in the long run.
