This is a Store Locator plugin for WordPress that incorporates Google Maps.
What it can do:
- Adds a custom post type called Stores for input of store locations
- Automatically retrieves Google Maps coordinates of location
- Lets you add a store locator in any page/post using a shortcode
- Search by entering city and state/province, zip/postal code or part of an address
- Shows results on right ordered by distance
