Tree Hugger Cloth Pads
For $2 a month you really can't go wrong! I have had some complaints of it not working properly but for the most part my customers love it. http://www.treehuggerclothpads.com
Used the contact form on this page but no response - not even an acknowledgement that they have received the message.
Edit: not sure the support link on this page works. Submitted a ticket here: http://shopapps.in/support/ and got an acknowledgement straight away. Problem solved within 48hours.
I have been using the app for a long time and it works well. They had some issues around Black Friday, however, they resolved the issues and have added more servers.
