1) We use 80/20 Aluminum Extrusion for our robot, so we're ordering something like $500 - $1,500 worth of Extrusion for this season, as well as tons of brackets.
2) Every variety of bolt and nut. Can't go wrong there.
3) Various Aluminum Sheeting and stock (square stock, flat stock, L stock)

That's pretty much all we're getting pre season but are considering also buying:

1) Mecanum Wheels
2) Belts
3) Sprockets
4) Talon Motor controllers
5) Polycarbonate
