Compare the three business-to-business buyclasses

What will be an ideal response?

The three business-to-business buyclasses are straight rebuys, modified rebuys, and new-task buys. A straight rebuy is a routine purchase of items that a business-to-business customer regularly needs. The buyer has purchased the same items many times before and routinely reorders them when supplies are low. A modified rebuy occurs when a firm wants to shop around for suppliers with better prices, quality, or delivery times. This situation also can occur when the organization has new needs for products it already buys. A new-task buy requires the buyer to start from scratch to gather information on purchase specifications. This situation requires the most effort of buyers and offers the most opportunity for new sellers.
