As one of its daily deals, That Daily Deal offers the Funko Star Wars Bobblehead in Boba Fett, Darth Vader, or Yoda for free plus $5.49 for shipping. That's tied with last week's mention and the lowest total price we could find now by at least $3. They're made of PVC plastic. Deal ends today.
Of note, Best Buy offers a different selection of Funko Pop! Star Wars figures for $5.99 via in-store pickup, as listed here.
