There maybe a few places that have it a dollar or two less but if you go to the ps3usbjailbreak downgrade thread there is a coupon that will have it delivered to you for under fifteen usd but it also takes at least two weeks for delivery. You can get faster shipping elsewhere but it will cost you almost double around thirty total for faster shipping so I always get.the free shipping.
