However as web evolved and economies evolved, a majority of web searches are to make a purchase(concert/bus/train/airline tickets, order food, buy anything off of amazon/ebay etc).
So for the times, when you know exactly what you are looking to buy. You are still sent of to different websites/app to look for best price. So there no knowledge graph like feature for shopping.
What if an app had your default shipping address, and knew all the card you have and then once you look up for an item it hunts the best price across all reputable sites and applies any discount codes. Also figures how you should pay depending on which card will get you maximum cash back.
Thoughts?
