From August 19 to September 8, pouring your coins at Coinstar doesn’t just mean cash in your pocket – you can also receive 20% off Amazon Apparel. Cash in $25 or more at a Coinstar kiosk and the code will be printed on your receipt. considering the number of people I see pouring coins into these kiosks, this is a great way to avoid the transaction fee and save 20% on Amazon apparel!
