Of course you can, Charlie. Just beware ~ they're not free.
Make-N-Take events are great, but the kits aren't donated. The kits are sold to promoters or sponsors in a large case of 25 kits - 24 are bagged and 1 is in the retail packaging.
Regardless, it is a great way to introduce kids to model building. However, repeat events will draw repeat participants who are there for the free kits. I'm not sure some of them buy a kit in between Make-N-Takes.
It's still a lot of fun, and even if only a few kids get the bug, it's worth it!
