Here you can purchase releases to be downloaded. Only Paypal is accepted at the moment on the site.
You don’t actually need a Paypal account to pay over Paypal. It’ll let you securely enter your credit card details and you won’t be charged a penny for the service.
Check the boxes next to the albums you want to buy and then choose between the Ogg Vorbis and MP3 formats.
When you hit submit you’ll be taken to a confirmation page before the data’s sent off to PayPal. There’s some more info about what you get for your dollars on the next page.
If you don’t know what the difference is, Google it. You should know that Itunes and Windows Media Player didn’t natively support Ogg Vorbis last time I checked but you can easily add support – see the Vorbis website.
