First, if you've got a debit card and it has a Visa or Mastercard logo on it, you can use it just like a credit card. There are two alternatives to a credit card purchase: PayPal or payment via money order or US check.
PayPal PayPal is a service which lets you pay via your email address and a password. If you don't have a PayPal account, vist www.paypal.com
If you have a PayPal account already, you can purchase our software from http://www.acoustica.com/paypal.htm
Depending on how your PayPal account is set up, you will receive a registration code from minutes to around 3 days.
Money Order or US check You can send us in an money order. You can usually have money orders made up at the post office or your bank.
