Use a sunglasses case to store cords and cables in your bag. I love using my old eyeglass cases. I use them all the time fo keep my jewelery in when I travel. and also for those cords for your iphone ipod, etc.
Save space in your wallet & organize all your gift & store rebate cards by putting a hole punch through them and adding them to a key ring. There are also "frequent user" card wallets available if the key ring is too much.
