By using the virtual store, you can shop at your local store or supermarket. You can also complete surveys and shopping experiences by choosing a product from the shelves and placing them in your cart. For you to begin shopping, your panel provider will have to give you a code that will allow you to do so. 
In this application, you will not be charged or receive any goods that you 'purchase' from the Virtual Store; it is only used for research purposes/uses. 
Try it now and participate by downloading this application; find out more info from Google Play Store.
