I've never understood why people use coinstar. I take a jar of coins to the bank and if I have an account with them, they throw it in their big coin counter and do it for free. Is this not a common service banks provide? I've only banked with a couple of banks (I'm in Wisconsin, USA) but they both do this.
Yes, but then I'd have to go to the bank just for that. The Coinstar machines are conveniently located in grocery stores and big box stores. And as dlhavema said, if you get your money as a gift card, it's free. Different Coinstar machines have different cards, but they all seem to have Amazon or Walmart.
