Its a brilliant idea that this price compares all items and finds the cheapest. But wouldn't it be nice if you could add and sort the cart to which items are cheapest in which ever store?

Then be able to have the app direct to that particular store with those items added to the basket?

Then after checkout you can go back to the next items in the trolley app and have these add to the next stores checkout basket and so on..

I find this app only useful if im going into store, not for home shopping/deliveries.
