Is there a coinstar where you can cash in your change

Yes

The iron mountain Shopko has a coinstar. It is better to go to shopko, they have the option of a Amazon gift code or other gift codes instead of a fee for cash.

Not sure if they do. But Shopko does.

I HAVE NEVER SEEN ONE IN IRON MOUNTAIN

The only place i ever saw one Escanaba Shopko

I am not aware of a coinstar in the Iron Mountain store.

In iron mtn walmart there wasnt one when i went in. The forward financial bank in the same parking lot does it for a fee if your not a customer of theirs
