Thread title is misleading. You only get one head and two different bodies. Still a pretty good deal for $64 shipped. Personally I would skip the diffuser and get the package from 4Sevens for $8 more because of their warranty policy.
Can't you give the money in cash to your parents or a close relative and have them order the flashlight online for you? That seems like a good option.. I wouldn't mind doing that for my nephew..
