Sears offers the South Shore Majestic Full/Queen Headboard, model no. 3107270, in Black for $70 with free shipping. (Walmart offers the same price.) That's the lowest total price we could find by $10, although we saw it for $13 less in December. It measures 64.25" x 3" x 44" and fits full and queen size beds.
