Need more info to rate.
Can have them send prints right to your customers instead of to you with $5 shipping, but only with a few sizes (source).
Free 2-workday shipping for most products.
Can set your own prices for prints, as long as they are above the base prices.
Handles selling directly to customer.
+$0.80 for adding Lustre to normal prints. Doesn't seem to mention this anywhere on the site except when I set the prices for my prints.
No free samples. Need Premium Account to buy your own prints at base price.
Prices don't seem to vary based on square inches.
