Scan Barcode to Reorder

Often we find ourselves in situations where something that we use is running out. It could be deodorant, toothpaste or just about anything else that comes in a container. There usually is a large variety of products for us to choose from, but I prefer to stick to the same brand if I am satisfied with it. However it's sometimes challenging to find the same exact product a few months down the road. Maybe the store has ran out, maybe they decided to stop carrying it altogether, either way it's no longer available when I need it. At that moment I could choose to compromise and try another product or brand, but I would prefer not to.

I would like to see an application which allows me to scan ordinary barcodes and automatically add the products to my shopping list. I could then choose to re-order and have them delivered to me before they run out.
