Home Depot offers the DeWalt 6.5-amp Heavy Duty Plate Joiner Kit for $169. Add it to your cart to drop the price to $144. (Amazon charges the same after an in-cart discount.) With free shipping, that's $5 under our May mention and the lowest price we could find now by $11, although most retailers charge at least $173. It features retractable anti-slip pins, a non-marring aluminum shoe, and preset depth stops. Deal ends December 25.
