Determining picking costs for a set of candidate products for a product order

A computer usable program product comprising a non-transitory computer usable storage medium including computer usable code for use in offering a set of candidate products that have a lower picking cost, the computer usable program product comprising code for performing the steps of:

• detecting a product selected for purchase by a user;
• identifying a list of proximate products to the product selected for purchase;
• utilizing a processor for ranking the proximate products considering incremental picking costs and applicability of the proximate products to the product selected for purchase to determine picking scores for a subset of the proximate products in the list of proximate products;
• and
• presenting to the user the set of candidate products selected from the subset of proximate products based on the picking scores.

A data processing system for offering a set of candidate products that have a lower picking cost, the data processing system comprising:

• a processor;
• and
• a memory storing program instructions which when executed by the processor execute the steps of:
• detecting a product selected for purchase by a user;
• identifying a list of proximate products to the product selected for purchase;
• utilizing a processor for ranking the proximate products considering incremental picking costs and applicability of the proximate products to the product selected for purchase to determine picking scores for a subset of the proximate products in the list of proximate products;
• and
• presenting to the user the set of candidate products selected from the subset of proximate products based on the picking scores.
