Since I’m a noob, and starting small, my goal is to make the minimum $25 needed to hit payout.
 
I don’t know if this will be helpful to anyone else, but I’m someone who likes to make charts to help me visualize. Realistically we get profit from all the different categories, but this break down helped me get an idea what I should be aiming for.  
 
Artist Profit on Bulk Orders:
 
1-4 card order            .60 per card            hit payout at 41 cards sold
5-24 card order            .56 per card            hit payout at 44 cards sold
25-49 card order            .50 per card            hit payout at 50 cards sold
50-99 card order            .46 per card            hit payout at 54 cards sold
100-199 card order            .30 per card            83 cards (guaranteed over payout)
200-499 card order            .27 per card            92 cards (guaranteed over payout)
 
Widget Commissions:
 
You receive .50 per card commission on the first 50 cards purchased by first time buyers through your widget. It would take selling 50 cards to a new customer to hit payout.
 
 
Hope this is helpful to fellow newbies out there : )

I love reading charts.  As wonderful as those bulk sales make me feel, this proves that I should be doing a happy dance for those one and two card orders (and I DO do the happy dance)!
