end of story. they're not that much more expensive than anywhere else and their quality is top notch which if you found the other post i'm sure you read. if for some reason they print a picture and the color is off they'll even reprint it for you. what more can you ask for?!
you can't really expect to pay nothing and get the best quality, can you? i've printed hundreds of photos through them and i haven't been dissatisfied with a single print.
