Described herein are predictions of consolidation between previously placed orders and potential orders in, for example, an e-commerce system. A consolidation prediction may include a determination of a cost differential between consolidating the potential order(s) with previously placed order(s) and refraining from consolidating the potential order(s). The cost differential may comprise a savings in shipping costs, taxes, handling fees, and so forth. In addition, this cost differential may be presented to the user. When the user desires to complete the potential orders, the previously placed order(s) and potential order(s) may be consolidated to a single order, merchant, payment type, destination, and so forth.
