Walmart offers the CAP Barbell 2" Plate Rack, model no. RK-2A, for $37.49. (Amazon charges the same.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $8. It holds 2" plates and features a weight capacity of 500 lbs. (It also includes a free 30-day trial of Daily Burn streaming workouts.)
