I don't buy directly from artist websites after being burned (no pun intended) once too often by CD-Rs which they
insisted were "real CDs". Although I love the idea of musicians keeping as large a percentage as possible of the profits from sales of their recordings, I have to say that most of them are gifted only in the area of music, not in running websites or home businesses

... so I just stopped buying direct.
And yeh, I've also experienced the "deluxe" website-only edition which ends up missing tracks that are released commercially.
(Sadly ... I think that the current music business model for many labels and artists deliberately relies on multiple purchases of the same title in order to make sufficient profits.)
