13Deals offers this Electric Bug Zapper Racket 2-Pack for $4.99 plus $1.99 for shipping. That's tied with our expired mention from three days ago as the lowest total price we've seen for a 2-pack. (It's a current low by $5.) It allows you to electrically incinerate bugs by swatting them in mid air. Two AA batteries are required (not included).

Note that they will ship in a random color.
