Walmart offers the Simplify 6-Shelf Sweater Organizer in Black for $8.19. Opt for in-store pickup to cut it to $7.86 and avoid the $5.99 shipping fee. That's the lowest price we could find by $18. It measures 12" x 12" x 47" and features board shelves and a Velcro closure.

Update: The price has dropped to $7.97 before in-cart discount, $7.65 after.
