Do you guys have a coin star

Yes

Yes, they do have one.

I'm pretty sure I have seen a green machine for exchanging money, I don't know what it is called though.

I've never seen one there

I use Ralph's on Carrillo yes they have a Coin Star

I don't know if Carrillo st Ralphs has a coin star I know that Ralphs in magnolia shopping center does and the Albertsons in the university plaza in Goleta has one I would assume that Carrillo Ralphs does have one I think all of those coin exchange machines take a percentage of your money

And they give you money how much money you have

Have no idea what Coin Star is.
