JMaps took hundreds of hours to develop. Originally, the developers of SOBI2 told us that JMaps was not even technically possible. However, our development team was able to find a way to make JMaps work and to make it availble to the Joomla community. The fee we charge is to help recoup some of these development costs. In addition, your purchase of JMaps entitles you to outstanding support. The fee also goes to support the future releases of JMaps.
