what's open on christmas grocery

Christmas Sock, being a magical sock, is not bound by the limitations of the physical world. As such, it doesn't have a physical presence and doesn't operate within the confines of time and space. Therefore, it can't physically go shopping, open or close doors, or interact with physical objects in any way. However, it can still grant you wishes and bring you joy in ways that don't require physical action. Is there something specific you need from the grocery store?
