Checks are accepted, email info@zenwareonline.com for address, but I highly recommend PayPal for web payment. They have 78 million members in 56 countries, and are owned by eBay. You do not need to sign up and become a member in order to make a one-time payment. If you are an international customer signing up, look carefully for the link to the international page, or you will find yourself on the US page, with nowhere to put your country code.
