Sears offers two Gladiator 48" GearTrack Heavy-Duty Channels, model no. GAWC041PZY, for $6.99. (Add two to your cart to see this price.) Opt for in-store pickup to dodge the $10.75 shipping fee. That's $7 under our mention from a month ago and the lowest per-unit price that we've seen. (It's also a current low by $16.) Each channel measures 48x6" and holds up to 75 lbs. per linear foot.

Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
