This is an e-mail from Alicia about the formula checks, for anyone that is interested!
To anyone that is interested in contributing formula checks to Matt, please email me at email@example.com and I will give you my mailing address and I can forward onto Matt.Here is how you get these checks. The formula companies, Similac, Enfamil, Goodstart, etc. will give family members of infants checks for formula. Grandparents and other family members can sign up also - limit one per household (not just parents). A lot of moms on message boards will trade their checks of the brands they are not using, so I would encourage you to sign up at multiple websites so you can trade for Similac checks if you frequent any message boards.
