I was at a Coinstar unit tonight with a bunch of change. I'm lazy about rolling coins, but never like paying 7-10% to someone to do it for me... but Coinstar has lots of e-certificate options that are free... so I was there to redeem for an Amazon.com certificate. But, I noticed there was an iTunes option... but the info was kind of outdated as it only referred to purchasing movies & music. I was wondering if anyone has redeemed any coins at a Coinstar unit for an iTunes certificate and then used that to buy iPhone apps? If so, then next time I might do that instead of an Amazon certificate.
