Yet another new mentor question - how much to order preseason?

[trycatch]

Since we're only a second year team (and last year fell on us right before kickoff), I'm still feeling a few things out. One is how much to stock up on stuff during the pre-season - with the six week build season it seems very prudent to stock up before build season gets going so you can hit the ground running, but at the same time knowing what the game is so you can spend more wisely would be nice to some degree to. How does your team handle this? How much do you do in advance vs. after kickoff?

Thanks for the input!
