• How many unique orders do we have?

• What is the most popular first item to add to the cart? Does that change by day of the week?

• What is the distribution of the number of items in the shopping cart just before checkout?

• What is the most popular second item?

• What department or aisle do users most frequently shop first/last?

• Create a bar chart of the number of items sold by day of the week.

• What department gets the most sales?
