I checked that out, seems like they are taking a lot of money (3.00), plus you have to buy the cards, so on 100 cards (.99) each, you taking 4 dollars out of the equation. You would still have to sell your CD's at $10 or higher to make the same amount as we do in stores now.
I think I like lambcase option better. Buy a pack of 100 cdr's, encode them in lambcase, put the decoder on there, GIVE them out, you only out .10 a cd. if they don't buy it.
you can do it yourself...my band did. Our web guy set it up that so that we could sell a password to download our album. Enter the password once and download the album and then the password isn't valid anymore. So now we can sell a t-shirt with a free digital copy of the album or even just cards with passwords on them.
