Answer

I live in connecticut and its 6.30 each here, but price depends on location. Not even available in all locations. Try the app, once you select your local store it will give you a exact price.

If I put about foot to 18 inches of gravel under block would it be wise to put 4 inch styrofoam under gravel

Answer

No, waste of time. You probably will not have a problem with frost heave, but if you are doing this with a permit you may have to dig a footing to code in your area.
