Not sure if anyone is seeing this too but
MP-02 Soundwave and MP-01 Acid Storm are on Toy r US ebay page and selling out within minutes everytime they put up a batch of 100 units.
Some people are buying 10 at a time and TRU seems like they keep putting up 100 at a time with a interval between auctions.
Keep checking, auctions selling out within 10-15 mins
