TW, I think you can toss 16ga ammo in there, along with 28 and 410, as being more expensive to buy than reload. Unless you're lucky and catch 16ga shells on sale--and then no one ever seems to have many of them--even the promos run higher than the 12's and 20's. But then reloading is no picnic either, because there aren't any hulls as good as AA, STS, and GM in 12 and 20. Wads are also more expensive.
