I've had a lot of friends ask me about the photo books that I make for my family. Hands down, Shutterfly has been the BEST photo site I have worked with (and I have worked with several).
I've also had them print off pictures (they have really good deals ALL the time), as well as Christmas Cards (great time to start planning that for sending). (I made a really cute Valentine's Day card for JD this year).
I really wish I knew about Shutterfly's Wedding Announcements when we got married. Seriously, so much cheaper than the invites we had done, and way cuter.
If you are into scrapbooking, they have recently updated their photo book department, giving you more options when creating.
Compared to the competition, Shutterfly's photo books have a higher quality of paper (I know because I have a book from another place and it is not as nice as my Shutterfly books). Shutterfly has very prompt deliveries as well. I don't think I have ever had an order rushed simply because I didn't need to. Shutterfly orders arrive quickly. And one of my favorite things about Shutterfly is that it's site is so easy to use (far superior to other sites). We are grateful for all of the options, and opportunities to explore our creativity on Shutterfly.
We love Shutterfly!
