There's a machine in our supermarket that will automatically roll your loose change, for a charge of about 9%. I'm amazed that people will pay that.

Also with this one, you just get a voucher that has to be used in the store.

I'll roll my own. Does anybody here use these machines?

My bank has a machine that will credit all my change to my savings account at no charge.  I can then transfer the money to my checking and their is no fee for this.  I would rather roll my own before paying a charge!
