When you first launch KavaTunes, a window appears telling you that the program is unlicensed. You can try all the features of KavaTunes for free. However, unlicensed copies of the program will only display artists whose names begin with the letters 'A' through 'E'. Click the Buy Now button to buy KavaTunes.
You can use either PayPal or Kagi to purchase KavaTunes. Both services are secure and accept credit cards from around the world. PayPal also lets you transfer money directly from your bank account, while Kagi accepts cash and checks. If you're not sure, use PayPal.
