Well so far I've tried snapfish, shutterfly, my publisher, printerpix and MIXBOOK...
And me (and couple of couples who I recommended them too..) came out that the best so far is MIXBOOK! I realy liked their layouts and needed the liest work done to have a beautiful book.
(Had one small problem with one of the features but can't recall what it was.. I think it was the auto save didn't always save my changes..) I found the Prog to be mostly easier and better then other ones.. And was very clear!
Printerpix only has leather for hard cover..
My publisher didn't come out very clear for us..
And shutterfly needed too much work!
