Amazon offers its Prime members the Lodge 10" Pre-Seasoned Cast-Iron Chef's Skillet, model no. LCS3, for $14.97 with free shipping. (Non-members can spend over $35 for free shipping; it otherwise adds $8.92.) That's tied with our mention from last month as the least expensive 10" cast-iron skillet we've seen. (It's also a current low by $5.) It's oven-safe and can also be used on grills and over campfires.
