Walmart offers the Star Wars Mini Lightsaber Tech Lab for $7.96. (Amazon charges the same.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $3. It includes parts to build an 8.25" version of Anakin Skywalker's lightsaber, including a lightsaber handle and stick, four crystals, two optic pieces, and manual.
