Shutterfly and MyPublisher recently joined .. I have used MyPublisher for a while to make photo books and one book of pages scrapped with DD supplies .. the MyPublisher books have always been spot on. Just got one in the mail today and it is pretty much the same as it looks on my screen .. very pleased. They have great deals most of the time and I usually snatch up a Groupon for their landscape size books. Maybe since the two have joined together, Shutterfly quality regarding brightness has improved. I still use Shutterfly for the free 4x6 prints they offer from time to time when my Mom wants "stuff" to put in her photo books :-) and there are still a few that are darker than I thought they should be. So I've started using MPix for individual prints that I plan on framing which I don't mind paying for those.
