Home Depot offers the Ryobi 40-volt Li-ion Cordless String Trimmer for $79 with free shipping. That's tied with our expired mention from two days ago, $50 off, and the lowest price we could find. It features a variable speed trigger, 11" to 13" adjustable cutting width, auto-feed string head, slim-pack battery, and 60-minute charger. Deal ends June 21.
