Selling formula issues

I’m getting pretty frustrated. I been trying to sell some formula. People who are interested, just ghost me. Like this is formula for your child. Im willing to meet them or whatever yet I still get ghosted. Not many people willing to meet you for what your child needs. It’s not like im over charging like I have pictures posted with a note, date and name. I know I cannot take back to the store bc I know the store don’t have the formula I do need. I have 3.5 boxes of the refill packs and 9 bottles of ready to feed enfamil gentlease neuropro. The only reason I have it is because I was gonna put my son on it but he don’t need it. Im not sure how to get rid of it at this point.

Update: I can’t donate right now or I would. I have to take the money and buy my sons formula with it.
