Patrick in Easton, PA wrote in to say he found the MTT Multi-Troop Transport for a mere $39.99 at his local TJ Maxx store! (They share similar toy inventory with Marshalls.) It's probably worth taking a look in your area if you're still in the market for this beast - I even saw one at my closest Walmart today, still at around $90 though. Good hunting!
While not fun enough to warrant $130, the figures alone are probably worth the $40 - you get some slug Battle Droids, some decent droids, plus Obi-Wan Kenobi and a ton of guns in this box.
TJ Maxx stores have stock of "overstock" TVC Wave 4 Attack of the Clones for a mere $4.99 each. If you're still looking for these, you may want to hit your local Maxx to score a good deal. Happy Hunting!
