coin star

you can go to coin star and put in all your loose change and they will give you cash, but they charge a fee.  They got to make money some how right?  No hard feelings, but i think I can roll my own change. I don't feel like giving away my money.  But I just found out that they have a new option.  you can keep all your money as long as you get a gift certificate.  So I scraped all my loose change and went on down to the nearest machine and got me a wealth of iTunes!  and I'm down loading it at Starbucks right now.  Can I plug any one else?
