For Prime members only, Amazon offers the Ozeri Stone Earth 12" Pan, model no. ZP3-30, for $21.68 with free shipping. That's $1 under our mention from a week ago and the lowest total price we've seen. (It's the best now by $4, outside the mention below.) It features a stone-derived non-stick coating.
A close price: Walmart offers it for $23.16 with in-store pickup.
