We made our money back 10 times over
We used the wplocalplus plugin to create our own business directory covering every town in the UK with 4 categories per town. Each page was generated by adding a search phrase, copying a shortcode onto the page then saving. We considered a free directory plug in but if we did that we would have to enter the data in ourselves. Using this plugin meant that our site was fully functional and populated with good data before we offered paid entries. We ran into an issue with the order of manual listings and in less than 12 hours the support team got back to us. Rather than giving us instructions they simply made the changes for us and sent an updated version of the plug in. The after purchase support was much better than expected. We have since used this plug in with a number of other sites and they are all generating additional traffic and revenue. This is an excellent purchase in my opinion and it is very rare that I pay for plugins.
