Purchase by finding the specific recording you want by using the search engine on the left or searching through the "Categories" on the upper left. Find each recording that you wish and click either on the drum corps name or on the button for each recording.
I will send the recordings to you via email. Usually you will receive an email with mp3s attached to it within an hour and certainly no longer than 24 hours.
PayPal is the method of payment. PayPal allows you to use your credit card as a "guest" so there is no necessity to sign up for PayPal. For those fearful of using PayPal, I have never had anyone have a problem with it in 10 years.
