For in-store pickup only, Walmart offers the Lodge 10" Pre-Seasoned Cast-Iron Chef's Skillet, model no. LCS3, for $14.97. (Amazon charges the same with free shipping for Prime members.) That's tied with last month's mention as the least expensive 10" cast-iron skillet we've seen. (It's also a current low by $11.) It's oven-safe and can also be used on grills and over campfires.
