This is a universal subset choice dataset, so it consists of a collection of subsets that are chosen from some universal set of items. Instacart is an online same-day grocery delivery service, where users order groceries through a web application. This dataset consists of a sample of orders from users living in the United States. In this universal choice dataset, we consider the de-duplicated items in a user's order to be a subset choice. This dataset was derived from the data here. Some basic statistics of this dataset are:

• number of items: 9,544
• number of subset selections: 806,662
