Here's the deal from the coinstar website:
|1.||Bring $30 of coins to a participating Coinstar® Center
|2.||Cash it in for an Amazon.com gift certificate… and get FREE coin counting!
Complete the printed receipt & mail in to receive your $10 Amazon.com gift certificate
So basically you get and extra $10 free if you wanted a $30 amazon gift cert. I did this and it was easy, and no fee for coin counting when you want an amazon gift certificate. Just have to mail in for the $10 by 11/08/07 – a date which is coming up soon.
