Private Inventory and High fee

Hi there ! I wanted to order private inventory becuase your team have bog delaying in procesing.
On your site I saw fees for my products is 0.20$ per sent order, and my agent add fees for me is 1$. 
Product cost 3.20$ on CJ, and on Alibaba I found for 2.60$ and with your fees should be 2.80$ and save me money, but this will  be 3.80$ which is more expensive than on CJ. Also, agent said me if I ordered 50pcs price will be 2.70$ +0.20$. 
Whats happening here ? Please explain me
Thank you soo much
