the last several years our small mall charged $7 bucks and let me then take as many pictures as I wanted. I do know that they were letting parents take photos even if they didn't buy one which I thought was nice but I felt worng doing that so we always bought one photo.
This year our Walmart was doing it for FREE!!! So instead of a group photo this year I got all the kids done individually for FREE!!!! I was so stoked!!!
