EGO has $50 off the 15in. 56V 2.5Ah Lithium Battery string trimmer at Home Depot B&M/Online for Free Shipping or Free In-store pickup. This is regularly $199.99, but has been on sale for $179.99 recently. This is a great price. Picked this up a couple weeks ago and very impressed so far. Power and battery are great for residential use.
