For the most part, the promotional "freebies" are random. You can put a request in the order notes, but depending on availability you may not get that specific item. On the several promos I've ordered on, I've only gotten one plug and one stand that were what I requested, though that could have been entirely random for all I know. And no, the ASP plugs are not compatible with the promo. It's the Lazerforge or the Elite plugs (mostly Elite). And yes, that is the "order notes" box.
