This extension is really outstanding. It is very much uncommon that a developer publicly responds by himself/herself on his/her 'Hobby Projects' about any issue and fix it and maintain it with so much responsibility. I am using this add-on for a very long time and it never let me down. As in India getting a Credit Card is so much troublesome that I could not donate to this wonderful project and I don't want to use PayPal. But, I hope, in couple of months I will be able to donate some money after getting my Credit Card. To the Developer, keep up the good work.
