I bet 99.9% of customers cannot tell the difference between prints made by a
1) lightjet
2) Fuji Frontier
3) Noritsu
4) $500 inkjet printer
According to your FAQ, you are using "Fuji Crystal Archive" paper, which many of your competitors use (Snapfish, for instance).
It looks like you are targeting yourself to a high end market, while your print sizes are 4x6", which is very strange.
Don't get me wrong, I don't want you to fail, I'm just surprised with your business model, it's really confusing.
One customer told us: "Shutterfly was really disappointing: pixelated, poor colors, and just a cheap feel - we'll never use them again." I quoted him in my post. Feel free to reach out to him to confirm.
As I mentioned in the post, 4x6 is just the start. We've only been working on this for 2.5 months :)
