Wayfair offers the Lipper International 2-Tier Metal and Bamboo 18-Bottle Square Spice Tower for $33.99 plus $4.99 for shipping. That's the lowest total price we could find by $2, outside of the mention below. It features spice names marked on the lids and magnetic clips that allow each section to be "flicked-out" individually.
Note that although the description mentions the jars being filled, this appears to be the unfilled model.
A close price: Quill offers it for $39.98 with free shipping.
