Kohl has more expensive bakugan prices than TRU, Walmart or Target but it is good to check all stores especially if you are looking for bakugan from earlier releases (2-4 months earlier from what target,walmart and TRU are carrying). I even found some older bakugan at borders but they too are expensive. The biggest frustration with this game is the lack of supply of certain bakugan. Like in our area it is very rare to see other types of ventus traps except for Baliton. Aquos and Darkus(I only see Ingram) bakugan are also a bit hard to find. Most boosters are either subterra or haos bakugan.
The major stores get their product by the case. Each case will have 16 pieces ( boosters or starters ). Also each case ( for that "wave" ) will have a predetermined sequence of Bakugan that are included. You just need to get their when they first get their stuff
This is fine if stores keep them in stock. The Walmart and target (2 stores) here in my area have basically stopped stocking them so its very frustrating once you figure out they all have the same thing. I was more happier visiting Kohl's because they had some releases from 02/09 and 03/09.
