I tried Shutterfly once, about ten years ago...
I had a "Groupon" for an 8x8" hardbound, glossy cover book for $10, so why not?
I was happy with the binding, and the reproduction was "ok", but the paper was definitely not photo-book quality.
Ten years on, the edges of the pages are yellowing.
I got my $10 worth, but I'd recommend doing research into paper longevity for a serious project.
