Get in touch with the Creatabrand team via email. Deal direct with no pesky auction or intermediary fees. The price you see, is the price you pay (USD). Includes all transfer fees and at least a year worth of registration. Then the domain is yours forever, or as long as you want to renew.
If you want to use the .com as your company name, it's up to you to do due diligence and register it in your country. As these are original names it's pretty unlikely they'll be taken, but best to check before you buy.
Payment is easy via Paypal. This your guarantee as you can claim your money back from them if you don't get your domain. But rest-assured, you will. It normally takes a couple of days but it can take up to a week or so to complete the transfer.
