FWIW - Both lenses were in immaculate condition. Only the original box was missing.
That's basically what I did for EF-RF control ring adapters (I bought two of them before the R5 came out) and the RF 24-105 L. I was annoyed enough about the way you get NO discount (and in fact have to pay one cent more) for the kit that I just bought a RP kit refurb. I got the RP for a net couple of hundred bucks more than a new 24-105 would have cost. Nice accessory for the lens!! Of course I've barely used the RP, but I seem to have bracketed Canon's mirrorless line, top and bottom ends at least until the R3 comes out.
I also don't think Canon care too much about the grey market, if they did they would do things to shut it down. Things like Nikon where they won't repair, even for money, cameras and lenses not originally imported by Nikon USA. Canon Japan owns Canon USA and as far as the world economics of the thing goes every sale is a sale to Canon Japan irrespective of the final destination of a specific body or lens.
