All of my ps3 controllers are dead and none won't charge. I need to buy a new charger wire thing..

Does anyone know how much they cost/where I can buy one from? Does gamestop or walmart sell them? & What's the exact name for them so I don't look like a fool trying to ask them where it's at

it's called a mini usb to usb cable
they sell them everywhere . it's the same type used for mp3 players , digital cameras etc. so you might have one already
cost is $5 or less usually , just go to the pc section of the store or the mp3 players and buy a cable off the shelf
