If you want to buy the physical CD
I encourage you to buy directly from Amongst Myselves (via your PayPal account). This certainly is a better way of supporting my work OR if you'd prefer you can buy from CD Baby and it's affiliates. Both set of links are below and are clearly labelled.
* Note that Non-Australian purchasers should use the PayPal-Int button.

If you want to purchase digital files of the audio
Then your best option is via CD Baby but there are numerous affiliates you can also purchase from.
