Which of the following types of auctions involves selling goods at wholesale prices?

Bulk auctions are specifically designed to sell goods in large quantities, typically at wholesale prices. This format appeals to buyers who are looking to purchase goods for resale or use in large-scale operations. By focusing on bulk quantities, these auctions enable sellers to move large amounts of inventory efficiently while providing buyers with the opportunity to acquire products at reduced prices, which may not be available in standard retail settings.

While the other auction types may also involve sales of goods, they do not inherently focus on wholesale pricing. Reserve auctions often have a minimum price that must be met before the sale is finalized, which can lead to higher selling prices. Online and live auctions can accommodate various pricing strategies and item types but are not specifically limited to wholesale goods.
