Brenda .. lately, the only time I order prints from Shutterfly is when I see the email offering free prints .. can't beat 'em for free if you turn off vivid. I have always turned it off whether for prints or books. I also ordered during the latest 101 free prints and my colors were pretty much spot on to what I saw on the computer. If you have already made your adjustments in photoshop/elements/lightroom then it is best to not let them make any other adjustments. Hope this helps for the future.
