I don't print all of our photos out. I have a nice digital camera that I received as a gift a while back so I can take great pics. For me it's more the hassle of having them developed. Maybe 5 years ago I actually used to print photos out on my home printer and not only is the quick expensive and quick to go but the pictures have aged very quickly.
So we usually go through our important family photos and choose the best shots. Then we get 50 or more developed when they are having one of those sales at Walmart or a drugstore, probably somewhere from every 2-4 months.
