You can buy them online in bulk for what ends up beings lots cheaper. 1000 balls that are 1 1/2 inches in size increases the surface area by 95 square feet, according to one website I considered buying from.
I thought originally my LFS was waaay overstocked until one of the guys there explained that even though the tanks are 10-20 gallons each and have many fish in them, the bio-load isn't what it appears to be because they are all connected to one huge filtration system, so he said to think of the tanks more like one huge divided tank. That made more sense to me. Maybe that is what your LFS has.
