If I haven't cashed a check before at Krogers can I cash my check there?

yes, there will be a small fee

You don’t need a Kroger card. It just saves you 50¢ on the $3.50 fee. But if you haven’t cashed before our 3rd party check cashing company might not let a big amount go through

You don't have to have a Kroger card. All you need is a valid driver's license

If you have a Kroger card you will have no problem. If you don't have a Kroger card, you won't be able to.
