Sears offers the Gladiator Gearloft 48" Shelf, model no. GAWA48SFRG, for $29.99. Opt for in-store pickup to dodge the $16.16 shipping charge. (Amazon offers the same with free shipping for Prime members.) That's tied with our November mention, which required pickup, and $18 below the lowest shipped price we could find. It features a weight capacity of up to 50 pounds.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
