1)For FRC Teams, there is a promo code that has a 30% discount. You buy Tetrix parts at the Lego Store.

FTC teams can go to the website EthanMiller already pointed out and when you prove that you're an FTC team you'll get the same discount.

2)10 business days, usually two weeks.

3)Identical battery meaning the battery must be the same battery used in FTC. It's a NiMH 10-cell batttery, it comes in black with a warning sticker(starting in late 2010), and red and blue (before late 2010) and says 'Orion 3000' on the sides. It has 20A fuses.
