Good place to aquire this year's game elements?

[Mongai]

Hello, our team wants to run our second year of our lego camp where we build robots in about a week and run FLL matches on the last day. We are expecting the same kids so we need to buy new field elements for this years game.

Maybe it's too early to go looking for a field and field elements, but does anyone know good sources to aquire these items? Or if one of you are willing to sell this year's game, PM me.
