I saw several of the legacy figures (mainly the Saga Legends, I think) that had a "Clone Gear" note, with a little thin white box inside. Well, I never bought a Super Battle Droid, and I needed one more figure to reach the $30 mark to get that "free" Holo Grievous. Opened that puppy up, and lo and behold, inside the box are about 4-5 guns/rifles. Cool.
Only way you'd notice is to open them up. So, if you need/want extra stuff, here's a way (like the old '80s Survival Kit mail-away). Especially if you have kids who lose their toys.
My question is, if others have opened theirs, did you find anything different than guns inside?
