Amazon has INSTEN for Apple iPhone 4/4S Sport Workout Armband – Black/Sliver for $2.83 with free shipping.
You can also get the Black and Light Pink version — if you prefer the pink — for $2.85.
I have a similar arm band and it is so useful for running – I couldn’t run more than a few feet without my music!
Thanks, Kansas City Mamas.
