Google Maps Plugin and Simplemap Store Locator plugin possible Conflict

Hi,
There is a conflict between your Google Maps Plugin and the Simplemap Store Locator plugin (http://wordpress.org/extend/plugins/simplemap/) in our website http://dev.psdgator.com/destinationskin/store-locator/
We get the following warning in all pages

Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.

and errors when using the simplemap plugin in http://dev.psdgator.com/destinationskin/store-locator/
After disabling the google maps plugin everything works great.

I would like to know if this is a known issue or if we could use a workaround , for example by disabling google maps plugin for that page only (maybe by modifying your plugin's code and by adding some conditionals).
Thanks in advance
