Is the Coinstar at this Jewel Osco still open for use? And does it charge a fee?

Yes it's working and yes it's a fee, but I will recommend to use the one at the TCF Bank, since I use it's no charge there. Next to the Atm.

Yes

They charge a fee I don't know if it's still open.

Fee about 12%

There is a fee, I would call and ask about if working.
