I use SmugMug to display photos for my clients. However, since I provide all pictures to my clients on a CD as part of my photo service, I don't actually use that site to have them ORDER pictures from me. I just want to make sure they can see the pictures in all their glory before receiving the CD from me.

So I'm not sure how the ordering part works there, but the display part is GREAT.
SmugMug is relatively cheap, I think, especially for me b/c I am not really "working" working right now. I am doing few jobs here and there, but a lot of times I'm not even charging at all! (I've done several newborn/maternity shoots for friends). But I love SmugMug even for showing pics to my family...the quality is SUPERB!
