What defines a bundle sale in a business rule context?

A bundle sale in a business rule context is defined by the requirement of selling multiple products together as a package. The definition often aims to encourage customers to purchase more items simultaneously, thus increasing the overall sales volume and providing added value to the customer.

In this context, specifying a minimum of three products sold at the same time distinguishes the bundle sale from other types of transactions. This requirement not only promotes inventory turnover but also creates a more compelling offering for customers who may be looking for a comprehensive solution or enhanced savings.

While the other options may describe different marketing strategies or sales promotions, they don't specifically capture the essence of what constitutes a bundle sale. Selling just two products or having a threshold amount like $100 does not necessarily implement the concept of bundling that focuses on accumulating value through a larger number of products. Additionally, discounts tied to a sale may attract customers but do not fundamentally define the criteria for a bundle sale itself. Thus, the choice emphasizing a minimum of three products effectively encapsulates the idea of a bundle sale in a business rule context.
