Walmart offers the Bell Child Star Wars Helmet in 10 styles (Darth Vader pictured) bundled with a Funko PoP Stars Wars Bobble Head in 13 characters for $19.99. Opt for in-store pickup to dodge the $4.97 shipping charge. That's at least $3 under the lowest price we could find for a helmet and bobble head in any of these styles shipped and purchased separately elsewhere. The helmets are CPSC 1203 bike compliant and ASTM F1492 skate compliant.
