Walmart offers the Whitmor 24-Pocket Over-the-Door Shoe Organizer in Pink, model no. 6636-1253, for $5.75. Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with last month's mention and the lowest price we could find in any color by $7, excluding the below mention. It holds 12 pairs of shoes.
A close price: Amazon offers it in Clear for $6.38 with free shipping for Prime members.
