Walmart offers the Ozark Trail 3-Piece Plant Oil Cast Iron Skillet Set with Griddle for $12. Opt for free in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $11. The set includes two plant oil pre-seasoned pans measuring 8" and 5", and a griddle of unspecified dimensions.
