I got so frustrated with this site I almost gave up on my project multiple times, so I cannot recommend it. This review should be taken with a grain of salt, because I never did go through and receive a final product but I believe there are too many limitations for Blurb to be useful to the casual photo/custom-book maker, mainly:
1.) You can't change the size of your selected book once you start making the book (ie. Started uploading photos). You can literally spend hours selecting and uploading photos, only to have to do it all over again if you find that your desired photo placement requires a portrait oriented book rather than a landscape oriented one, or if you need a bigger size book etc.
2.) The bookify interface is simply not very user-friendly. It takes ages to figure out how to do things that should be clear, like, how to delete a photo, or move a page in your book arrangement.
I also can't recommend the website because although I bought a groupon that said I had $45 to use towards any custom-book project on the site, Blurb tried to charge me separately for shipping. Note that according to my groupon, only tax and gratuity were excluded. There was no mention of having to pay $8 to $20 extra for shipping, even if I had enough groupon promotional credit left over once my book was finished. I tried to sort it out with Blurb's customer service, but was not satisfied with the weasely way they tried to insist shipping was not covered by the groupon's value. I ended up not finishing my project, and instead called up Groupon, who gave me a refund.
