Donating Formula Samples

I'm asking this here because it is directly related to a hot button issue. I would also like to state this is not a breast vs bottle issue, this is not about what I should do with the stuff I have already received (I have my mind made up on that) this is about the morality of the issue of signing up just to donate.

I plan to breastfeed my baby. I have received formula coupons and samples in the mail and as part of the welcome package from my OB's office (it had breastfeeding stuff in it to before someone gets huffy).

Since I intend to breastfeed and won't be using these coupons and samples I plan to donate them. Here is the moral question: would it be wrong to sign up for the coupons/formula checks, etc that formula companies seem so willing to give out, just to donate them to the local food pantry?
