But others on reddit claim this is not the case. And their faq, policies, product description, and checkout page make no note of this at all.

Not just no note of background checks, but no note of restrictions of any kind.

There are many words about international shipping and related restrictions. But no “you need to be a doctor” as far as I see anywhere.

This is either a “reddit being reddit” situation, or skulls unlimited had a change in their policies in the past.

For that price, it's gonna somehow have to be included in _every_ holiday.
