Walmart continues to offer the Ozark Trail 3-Piece Plant Oil Cast Iron Skillet Set, model no. G2608-A22, for $19.88. Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with our mention from last week and the lowest price we could find by $17. The set includes three plant oil pre-seasoned pans measuring 8", 10.5", and 12".
