Kmart offers the Presto PopLite Hot Air Popcorn Popper, model no. 04820, for $13.49. Opt for in-store pickup to avoid the $5.75 shipping fee. (Amazon has it for the same price for Prime members.) That's the lowest total price we could find by $6, although we saw a used unit for $7 less in September. It makes up to 18 cups of popcorn in less than three minutes.
