If you've got a lot of coins lying around (at least $30), then you should take advantage of this Coinstar promo where you get a free $5 Amazon credit! All you have to do is pour at least $30 into a nearby Coinstar and choose the Amazon gift card option at the kiosk. You'll then get a unique Amazon code that you can redeem online.
I gotta admit, this is a better system than my current method of coin disposal. I save quarters for laundry, dimes for sugary snacks at midnight, nickels just kinda get lost all over the place, and pennies are thrown out my window at cars honking before sunrise.
This promo expires on December 31, 2020.
