I guess we luck out ... we get proofs of the photos before we have to order & pay, and one of the specials that they do is a photo retouch (scars, acne, dirt, etc) for $6. They also do vignettes, different tones (B&W, Sepia) and offer portrait or landscapes. Plus I can go online and order so many extras with their photos (we are given a code with purchase). Could also get all photos on CD too.
I have only gotten a few of the kiddos school pics in the past, haven't done every year. This year, I got 1 8x10 of each kiddo, but we get to take advantage of a family package - third and each additional child is half off, so I got all four kids for the price of 3. Can't remember right now how much it was, but it wasn't too bad.
