I tried to look for this, but maybe I am using the wrong terminology.
I am trying to find a plugin/widget/etc. That will integrate into my company's website (running wordpress), that can tell customers where they can buy our products based on their zipcode. I am sure many of you have used this feature on another website, I would like to have one that can be integrated into WP. If anyone knows of one, or could make one, please contact me.
