System for a three dimensional shopping cart

A computer for implementing a method of purchasing quantities of items using a 3D shopping cart, said computer comprising:

• a processor configured to:
• receive a listing of items selected for possible purchase from one or more external e-commerce systems through an API;
• identify characteristics of each item in said item listing based on data points acquired for each item from one or more data stores;
• identify an item type for each item based on said data points;
• identify shared characteristics among a plurality of said items;
• generate a 3D ordering of said plurality of items, wherein said items in said 3D ordering are visually arranged according to said identified item type and said identified shared characteristics of said items, thereby forming a 3D shopping cart,
• wherein the 3D ordering has a 3D shape defined, at least in part, by the number of said identified shared characteristics among said items, such that the shape has a number of axes corresponding to the number of identified shared characteristics.
