The strategy is most successful when:
Product bundling is most suitable for high volume and high margin (i.e., low marginal cost) products. Research by Yannis Bakos and Erik Brynjolfsson found that bundling was particularly effective for digital "information goods" with close to zero marginal cost, and could enable a bundler with an inferior collection of products to drive even superior quality goods out of the market place.
In oligopolistic and monopolistic industries, product bundling can be seen as an unfair use of market power because it limits the choices available to the consumer. In these cases it is typically called product tying.
Pure bundling occurs when a consumer can only purchase the entire bundle or nothing, mixed bundling occurs when consumers are offered a choice between the purchasing the entire bundle or one of the separate parts of the bundle.
Pure bundling can be further divided into two cases: in joint bundling, the two products are offered together for one bundled price, and, in leader bundling, a leader product is offered for discount if purchased with a non-leader product. Mixed-leader bundling is a variant of leader bundling with the added possibility of buying the leader product on its own.
Bundling in political economy is a type of product bundling in which the product is a candidate in an election who markets his bundle of attributes and positions to the voters.
