Organization Buying

Organization buying: 

Organization buying is the bulk buying that an organization does for resale or manufacturing purposes.
In Amul,Dairy Cooperatives in Gujarat have created an economic network that links more than 3.1 million village milk producers with millions of consumers in India. These cooperatives collect on an average 9.4 million litres of milk per day from their producer members. Since the raw material for dahi is milk, this is the only item that is bulk bought.
Another example  are the retailers that buy Amul Dahi in bulk to sell in their shop. Bulk buying helps in getting the buyer better and cheap prices for that product.

Also it helps Amul because they sell large volumes of butter. For example: Amul sells its small 200gm packs to airlines or railways in huge numbers, hence it helps Amul in terms of volume, it also helps the buyer because since they require only small quantity, these packs are perfect for them. Overall its a win-win situation.
