Selling Milk?

I have over 600 oz of frozen breast milk in our deep freezer from pumping while at work. Since I'll be staying home, I wont' need that much frozen breast milk. I was looking up how to donated my extra milk and came across a website that lets you place an ad for free to sell it. I thought I would give it a shot and see if anyone wants it. The ads I looked at are selling the milk for $1-$3 per ounce. That means if I'm lucky I can sell my extra for $600-$1800. Any thing will help at this point. Not sure if anyone will want it, but you never know. If not, I'll donate it a hospital.
