Of note, Home Depot offers the HDX 5-Tier Ventilated Plastic Shelving Unit, model no. 17601099, for $34.97. Choose in-store pickup to avoid the $7 shipping charge. (Ace Hardware has a similar one with wall mounts for pennies more.) That's tied with last week's mention and $20 under the lowest total price we could find for a similar shipped unit elsewhere. It features wall mounts and measures 18" x 36" x 72".
