I'd like to add a wish to this list. At this moment I can't install Calibre Companion, because I cannot pay for it. Where I live, credit cards are not as common as in other countries, such as the United States. I'm one of many people who doesn't have one. Could you therefore add PayPall as a payment method?
You might consider adding PayPall as a method for supporting Calibre as well.
Thanks in advance.
