Ad is for cases of Neocate One Plus Formula. I have 10 cases total to sell. These sell for over $100 ea. from the store. cases are all brand new.They are $30 ea. case but If you want multiple cases I will give you a better price. This is a formula used mostly for special needs children, or children with multiple food allergies. If you are looking at this post you probably already know all about this formula but if you have any questions please feel free to contact me and I will answer any questions promptly.
