Sales Baskets

Details about a shoppers basket contents. Basket is a term meaning each individual sale. For statistical purposes seperate sales that we strongly believe are the same customer may be combined. For example if sale #1 is to Bob for X,Y and Z, and then 30 seconds later there is sale #2 to Bob for J, these may be combined and treated as one basket when reporting. The reasoning being they either were prompted to buy something else, or are splitting sales for some reason
