Let's see... I paid about $18 for it. Not sure how much of that DA keeps... You know what you should do to decide though? Put a poll up asking if people would be interested in buying prints of your work. FTW!
Um... I don't know how it works for you.. I paid monies on my end, I suppose they would have to pay you a percentage of that either in money or points.. Right now my order is in the review stage it says so I am guessing once it is actually produced and sent to me, you will see a return on your end.
