Reader Meredith let me know about a deal at Coinstar Centers. When you deposit coins and use $40 or more to get an iTunes certificate, they will send you a bonus $10 iTunes card via mail. You can go here to find out all the details.
This is a great way to use up loose change and score some gifts for birthdays or the holidays.
You can go here to find a Coinstar Center near you.
(thanks Meredith!)
