I always am buying new beyblade stuff but from the same stores and only one place is local so I do not have many choices im wondering if you are suffering the same problem?
I'm sure you didn't need a thread for this but not many places do sell blades near me that's why I buy mine off eBay.
I also dont think this needs a thread. I think it can go under Ask a Question Get an answer thread. Anyways the beys sold depends on whats the store(department, dollar, local, etc.) , your area and if it is very popular in your area. If they dont sell good stores wont sell them. SoI suggest this thread be closed.
How many toy stores are in your region is totally up to your own city.
