Shopping – It’s possible that there could be something to it (no idea- never heard such a thing before), but IF there is, it’s some kind of kabbalistic concept with a much deeper meaning, and not meant to be taken in any kind of literal way. And not something that we should be concerning ourselves with, especially if we have no idea what the deeper meaning is and are unlikely to ever understand it. AND we don’t even have a source and have no clue if there’s even any truth to it.
At least that’s how it seems to me, but I could be wrong.
