Auction Houses are websites that earn income from the sellers, buyers, and from advertising. The first established and currently most popular auction house is eBay.
The way an auction house works:
PayPal is an e-commerce business allowing payments and money transfers to be made through the Internet. It serves as an electronic alternative to traditional paper methods such as checks and money orders.
Business to Business Auction Houses are used to dispose of unusable or excess inventory.
Seller-Bid Auctions and Group Purchasing Sites are driven by the consumer, rather than the seller. Seller-Bid Auctions are a reversal of regular auctions, the seller "bids" for the buyers business.
Specialized auction sites such as Onsale.com and Ubid.com deal primarily with online bidding for name brand technology equipment.
What is the difference between Seller bid auctions and regular auction houses?
