Using the store ranking filter on the right-hand side of the screen, we focus on the top 20 performing stores during the promotion, which account for almost 60% of total unit sales in the 57 participating stores.

The store class table indicates that unit sales were fairly evenly distributed between store classes. The colored circles in the unit sales by store & weekday graph show the distribution of unit sales for the top 20 stores (grouped by store class) by weekday.

The absolute DSI by weekday graphic indicates that sales were greatest between Friday and Sunday. Many stores indexed at between 130% and 150% of the 7-day average of daily unit sales at each store. In most of the 20 stores, unit sales declined to between 75% and 85% of the 7-day average at each store between Monday and Thursday.
