Walmart offers the GreenWorks 7-amp Electric Leaf Blower for $22.08. Opt for in-store pickup to drop it to $16.20 $15.56. (Amazon offers it for the same price for Prime members only.) That's the lowest price we could find by $4, although we saw it for a buck less two weeks ago. It features a maximum air speed of 160 mph and cord lock that prevents the cord from disconnecting.

Update: The Walmart item is no longer available; however, Amazon still has it for $15.56 with free shipping for Prime members.
