Do they carry sport cards at this store and any ideas where they are stocked?

Yes

I believe if they do carry any that there is the smallest selection around only because they don't usually specialize in sports cards or memorabilia at wallmart they just generally carry a small variety of basic everything.

Yes. Ask a worker once u walk in the greeter should be able to point u the right way. Very helpful staff at this location.

Yes and yes
