Google knows when you've been looking up a particular device or product through its search engine, because that's targeted advertising gold. Now there's a new card in Google Now that helps you turn fantasy into reality by telling you where you can get that thing you've been searching for in real life.
The card will only be triggered if you're out someplace and happen by a store that has the product you've been searching for. The card for this might contain multiple products from multiple stores, each with a price listed.
The functionality seems to have just shown up in the most recent Google Search update – we noticed a new product card layout in the teardown, but it wasn't clear if it was active yet. We have an answer now.
