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
