Kmart offers the Basic Essentials 3-Piece Cast Iron Pan Set for $17.99. Opt for free in-store pickup to avoid the $5.75 shipping charge. That's the lowest total price we could find by $38, although we saw it for $4 less in November. Sales tax is added where applicable. This set includes 6.5", 8", and 10.5" pre-seasoned cast iron fry pans.
