Icydeals via Amazon offers Prime members the Swivel Store Organizer 4-Pack in White for $13.99 with free shipping. (Non-Prime members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $7.02.) Aside from the mention below, that's the lowest total price we could find by $10, although we saw it for $4 less in June. Each organizer holds up to 20 standard size spice bottles.
