I have had my pal for a few weeks now, and looking to make my first purchase with it. I've known the rifle I'd like to purchase for quite a while, a non-refurb SKS with a red cherry stock. The seller requests I send him the physical original of my PAL card. Is this common practice? Is it legal to send a scanned copy of my PAL Card? It seemed fishy to me, to send my physical copy across the country as proof that I own the card.
