I have a family friend traveling for a few days to Edinburgh and Dublin. I’d like to ask him for a favor and check a few stores that might have some British creams/soaps (MWF, Cyril Salter etc.) my friend is not into wet shaving and has no idea about any of this. Are these items and others similar to these attainable in regular stores or do you have to go to very specific shaving boutique stores? Thank you.
