The Bass Pro shop in Mesa, Arizona shows Barricade in a aerosol can @ $11.99 each.
I mention this because if it is available at one Bass Pro shop, it should be in the dealers catalog at all Bass Pro shops so, you local store should be able to order it for you.
Brownells is offering Barricade in a 4 1/2 ounce can for about $7.

I don't know what their postage is but that can will last you for years.
You don't pour the stuff onto the gun so it isn't like taking a oil can and giving it a couple of big squirts.
All it takes is one light coat of the stuff to do the job. You do this by dampening a patch and then wiping it on the metal, both inside the bore and on all the external surfaces.
After it is applied it will seem to evaporate but it is still protecting the surfaces.
That is one of the neat things about the product.
Because it seems to dry, it won't effect the powder charge the next time you load.
You don't have to wipe it out before loading.
It will not cause any hard fouling if you use this method.
Get some. You will be happy.
