​You are selling a 170$ USD Wordpress plugin (Availability Image Map) and after installing it we need to install another 19$ USD plugin (​Page Builder by AZEXO) and after this one it asks me to install another ​29$ USD plugin (Mynx Page Builder) to make it work? I'm not willing to pay for that last one because I'm afraid you'll ask me to buy another plugin right after... Never seen this before... How come required plugins are not included in the main plugin???​
