With orders of $25 or more, Amazon offers the Friday the 13th Jason Voorhees Mask Ice Cube Tray for $6.92 $6.96 with free shipping. That's the lowest price we could find by $6. It's BPA-free.

Note: This item is part of Amazon's "add-on" program and can only be purchased with orders of $25 or more.

Update: This is no longer an add-on item, and so Prime members bag free shipping at the price above.
