Hi duruihit,
As I have mentioned, the manufacturers strictly control the distribution of these milk products, as baby formulas require strict regulation and FDA checking. If you wish to become one of their authorized retailers/distributors you need to get in touch with them directly. Below are their contact numbers
Enfamil (Mead Johnson)1-800-2229123 | Mon. - Fri. 7 a.m. to 7 p.m. CST/CDT | Sat. 8 a.m. to 4 p.m. CST/CDT
Similac (Abbott) 1-800-232-7677, Monday through Friday, 8 a.m. to 5 p.m., CST/CDT
Bright Beginnings (800) 410-9629 Monday - Friday 8 a.m. – 5 p.m. EST
Hope this helps. :)
