That's great! I'm happy for you...so many collectors still can't find any of those three Expanded Universe Vintage figures and Malgus was part of the third wave of the year all the way back in, oh, March.
Sounds like someone might have been trying to hide them to come back later and pick them up, but that's a lousy way to do it. A kid or collector would be much better off hiding them behind some boxed vehicles or even in the girl's doll aisle behind some Barbies than leaving them on the SW pegs. Collectors know to check every figure on the pegs, even the ones at the very rear.
Congratulations! A whole lot of people are still trying to get those characters.
