Agricultural Portal for the Support of Preferential Purchase and Cost Effective Sale (AgriPortal) The main objective of the portal is to facilitate cross country preferential purchase and cost effective sales in various agricultural sectors. Using the portal farmers and farms (of smaller size) could mitigate their purchase disadvantages inflicted upon by the negotiation power of buyers of large volume agricultural products. The portal will enable small and medium sized farms to join forces and make large quantity purchases thus obtaining discounts. The system will also facilitate the sale of purchased but remaining, not used products. Registered farmers and producers (even distributors) could sell their remaining products through the system operating as a classified advertisement portal
