Brakn -- check out online stores such as cdstreet.com, cdbaby.com, or efolkmusic.com. They will provide you with a page to advertise your CD, put up soundclips, etc. At least one of these gives you the option of sending them inventory to ship, or shipping from your house after they notify you they have a buyer.

These sites get a lot more traffic than your own website will, and you can set up crosslinks between your site and the store.

As an example, go to my site, click on the "order" button, and follow the link.

Cheers,
Michael
