Don't know exactly the coverage on the stores (I wouldn't waste the money on shipping) But for any future people reading this post you can get an anvil shaped chunk of cast iron 50-100lbs depending on what they're selling at the time from harbor freight. I wouldn't recommend it as a first choice particularly, but it'll get you going and if you don't beat the hell out of the face (which you shouldn't do to a steel-faced anvil either) it'll last you for awhile. The seem to run $1/lb or less and mine needed a significant amount of grinding on the horn to get it to a decent shape, but for the small amount of time I have to devote to forging right now it's a reasonable compromise between cost and value.
