When you get 'em home, wipe them down with some cooking oil real good and throw them in the oven for an hour or so around 325F, then let them cool down to room tempurature. That will seal and season them as cast iron is quite porous.
Keep repeating that process for several more times after each use until they turn jet black over time.
I would suggest one additional step. Before wiping them with oil (I like Crisco in the can) Wash (scrub) them well with hot water, soap, and a brush. Most come with a coating of oil or wax that you need to get off before seasoning. Don't put too much oil on the pan - Your smoke alarm will go off

Use about a table spoon of Crisco. Wipe the skillet all sides and handle. Turn it upside down in the oven with a pizza pan underneath (next rack below) - so the oil can drip out. I season mine in the grill outside. Keeps the wife happy.
Well, that's far more than I really know about Cast Iron.
