Enter the Coinstar Exchange Kiosk. Located in grocery stores across the United States, they provide an easy way for you to convert your loose change into viable currency. They let you convert the value of your coins to cash but will assess a hefty 10 percent fee. The better option is to convert to Amazon credit, which does not incur the fee. Simply dump in your change into the machine and out comes a small receipt with a code you can use with your next Amazon purchase. Other retailers and restaurants are available, but I trust you'd rather have a new model than take your family to dinner.
Some of you already know the value of Amazon as a source for plastic models. For those of you who don’t, you’d be surprised at what you can find there, often at prices competitive to those you see at your favorite online retailer. (And at least one prominent online retailer has a presence on Amazon.) For example, you can buy the Academy 1/48 F-4B for $49 with free shipping, the Airfix 1/48 Defiant for $34.99, or the new Takom AMX-13s for around $43.
It’s not unusual for me to amass $25 in change every month, which can easily be applied toward a new kit. Unfortunately you can use only one credit code per purchase, so if you want to buy that new 1/350 aircraft carrier you’re gonna have to save your pennies for a long time.
You can find a Coinstar location near you on their web site. Happy hunting!
