Obvious question… but has anyone experienced first hand heading to the aforementioned FS shops above, when your interest is ONLY with a BJ / 69 etc.?

Yes - i’m sure you can just roll in there, pay the fee and just tell them what you want… but curious of first hand experience from brothers who have done this, or do so typically. Would imagine it is quite rare, but also… why not if there is a gap in the market?

Best of luck to the OP with his visit. Follow the advice above, as well as your prior positive experiences.
