That's $20 brand new. If you get it used you can find some either for free or next to nothing. I don't think it's a cost thing, I think it's an accessibility thing.

Also, Kellogg isn't a budget cereal brand. If you're so poor you can't afford a few dollars for a ride cooker then you shouldn't be buying Kellogg. Actually, nobody should be buying Kellogg because it's all the same cereal except for marketing.
