We have found that googling Lodge Cast Iron turns up many places who sell it, often on sale and with free shipping, worth the time to look if you are ordering something.
We have used our 8" several times now, and it is the perfect size for the two of us. A jar of Cracker Barrel cobbler filling with a topping is just enough for dessert one night and breakfast the next morning.
Pillsbury crescent roll dough with a little cinnamon sugar on top makes a nice, easy topping, everything bakes up in 20-30 minutes.
