This is the number of weeks when a given product was in the Circular/Leaflet/Flyer (Feature). Features are used by retailers to communicate savings to their shoppers and try to drive shoppers to make a trip to their store to take advantage of the savings. When looking at Feature weeks across an aggregated geography, you will see the average weighted Feature weeks. For example, let’s take two equally sized retailers: if one had the product in the Feature, and the other did not, the Feature weeks of support for that product in that week would be 0.5.
