Home Depot offers the HDX 4-Shelf Plastic Ventilated Storage Unit in Black for $19.88. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from two weeks ago and $5 under the lowest price we could find a similar unit elsewhere. It features a weight capacity of 150 lbs. per shelf and 600 lbs. in total.

Update: It's now available for in-store pickup only.
