Need online store available without logging in

We have items that we sell that it would be nice if they could just be available for purchase without creating an account. If a relative (grandma, aunt etc.) wants to purchase a star gram or customized ballerina bear I don't want person to have to log in to purchase for the dancer. Even the qr code that is generated with current item does not allow for direct purchase just shows an item #. I would like to get rid of old payment system for the extra stuff that we do.
