Are Transformers figures sold here? And if so, what kinds? Regular ones sold at Walmart or more high-end ones?

I don't remember seeing any Transformers being there. Sci fi is more of a specialty store. They might have Transformers comics.

If they have them the will be high end. They can probably find what you want.

There is some high end ones, transformers are typically special order

I frequent sci fi factory and I haven't seen any transformers. But you might can have them order them and maybe get them that way.

I've not seen any transformers at the Keller location. You might call though, they do buy and sell collectables, and should be able to point you in the right direction.
