As one if its daily deals, Groupon offers the LEGO LED Flashlight in Darth Vader (pictured), Stormtrooper, or Dynamo for $9.99 plus $2.99 for shipping. (Orders over $15 bag free shipping.) That's $3 under our April mention and the lowest total price we could find for any of these styles by $11. The Dynamo flashlight is powered by a crank handle, but the other models require four AAA batteries (included with the Stormtrooper flashlight, but not the Darth Vader model). Deal ends May 22 at 1 am ET.
