Target offers the Lodge 8" Pre-Seasoned Cast-Iron Skillet, model no. L5SK3, for $9.53. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $4 shipping charge. That's $2 under last month's mention and the lowest total price we've seen. (It's a current low by $10, excluding the close price below.) It's oven-safe and can also be used on grills and over campfires.
