Northern Tool offers the Ironton Steel Hitch-Mounted 4-Bike Rack, model no. 41157, for $79. Coupon code "248528" cuts it to $69.99. Opt for in-store pickup where available to avoid the $18.49 shipping charge. That's $10 off list and the lowest price we could find, although we saw it for $40 less in February. It converts from a two-bike rack to a four-bike rack and handles up to a 120-lb. load. Deal ends October 18.

Update: The price has dropped in-cart to $49.99, making it $39.99 after coupon.
