Plenty of stores let their customers search for the nearest location around them on their site. The Find Your Nearest plugin adds such functionality to your website. It lets you create as many entries as you want and allow your visitors to find the nearest location around their home.
This plugin is powered by the Google Maps API. Once you have created your entries, your visitors will be able to search through them by entering their own postal code. You can change distance units, search results page, country, and other settings in the back-end.
