Today i did a search for the online Staples site (computers/software/office supplies). And, the first listing up was for the official online Staples store. But also in the sub-listings was the exact address of the Staples store which is just down the road. Felt kind of weird how Google would just know where my local store should be. I don't remember including my zipcode on anything Google related. I know they have ways of knowing a user's geographical location but it's just creepy when they do that.
