What happens to the 2016 game pieces?

[AriMindell]

I am going to be head of programming on my team next year, and I wanted to start preparing by overhauling our 2016 robot code. As any coder knows, it's impossible to write successful code without testing, and in order to test, it would be helpful for me to have some of the real game elements to play with. I figured, what could FIRST possibly need the game pieces for, now that the season is over?
I know that full fields are available for rental from AndyMark for off season events, but I am more interested in having just a defense base and a few defenses to play with. Is it possible to purchase the previous season's game Elements? If so, how would I go about doing so?
