Amazon has the LEGO Star Wars BrickMaster Exclusive Mini Building Set #20021 Bounty Hunter Assault Gunship Bagged on sale for just $8.99 (was $30). This item also ships for FREE with your Prime membership, or with a qualifying order of $25 or more.
From what my son tells me, this is a Brickmaster Exclusive so it can be difficult to find. 😉
Thanks, Mojo Savings!
