Isomil Soy formula babies near commack ?

We had a small sample size can. I was about to give it away last week, and my MIL was babysitting and opened the can, think it was our regular formula.

now i feel bad throwing it out.
If anyone is nearby the area, and can use it.
It Similac Isomil soy, small powder can.

I think once opened they are good for a month.
