I have also done this MANY times over last three years. When BHN or InComm stock these cards at store they themselves do not keep records of the SKU numbers sent to each store. That’s why you can swap and purchase same brand cards between different stores…..Kroger, Safeway, Vons, Ralph’s, Albertsons, CVS.
How I know that SKU are not recorded is that when a card won’t load at purchase, the card is just tossed by the store, which has been my experience quite a few times.
