Have you tried to buy Bakugan toys? Talk about popular: Amazon's sellers are nearly sold out and customer comments indicate that prices have been rising as the holidays draw nearer.
Then there's the Wal-Mart "Site to Store" secret. I was in Wal-Mart yesterday at 9 am to buy Bakugan. Employees in the toy section sent me to the hidden "Site to Store" pickup area, part of a stock room off the main selling floor. IF the store has any Bakugan items in stock, you can buy ONE of each kind at a time. That's exactly what I did. Better hurry--inventory is limited. Bakugan seems to be muscling its way past Pokemon.
