An example of the Buyer Aggregator model is a site that pools the purchasing power of buyers who have a common goal of purchasing and receiving a discount on goods and services, and then connects those buyers with the sellers of those products and services.
Buyer Aggregator Model describes buyer aggregation as the process of bringing together individual purchasers from across the Internet to transact as a group so they can receive the same values traditionally afforded to organizations who purchase in volume. Sellers pay a small percentage of each sale on a per-transaction basis.
