On a kids income Iwould see if you can get an old school locker or two. These are cheap or free. Contact the schools or run an ad.

This is actually a great idea! Never really thought of it. The one white tail posted is not bad either. It's the stack on I bought for $99. I worked until I could afford a real safe. Now I use it for ammo and cleaning supplies I don't want my kids to get to.
