I didn't keep a record on the toy checklist of bundled TFs, because it wasn't really a packaging variant (minimum requirement of the checklist). The one thing I just thought of though, is go through the sightings and AU news sections of the old board (while it's still there), and look for any mention of bundled packs. It might take a while, but it's an option. But I can't think of anything else off the top of my head though that you didn't already mention.
