Just loaded and tried the FutureShop app on my iPhone.
Searched for a camera I am likely going to buy - Panasonic Lumix ZS7. Found it and displayed some details. Options to add to cart, add to wish list, or Share. And you can see user reviews of the item.
You can use your current location to see which stores are close.
What you can't do is see which stores have the itme you are viewing in stock. Maybe that comes up if you put the item into your cart, but I am not going to buy online, so I don't know.
