Instead of rushing to the mall for your Santa pics, turn to your local community instead. Just this morning, I passed a Christmas tree lot that advertised Santa pics. You can find local churches and community centers that host a Santa event for a fraction of the cost or free.
Last year, one of our local high schools hosted a Breakfast with Santa event to raise money for the band. For $5 per child, each of my kids got a pancake breakfast plus an individual photo with Santa. So, for $15 all my kids had a breakfast, and I got 3 photos. This year, we went to our local Parks and Recreation Center and paid $10 for all the kids to get their photo taken plus access to the craft show. Plus, I took about a dozen of my own photos on my camera.
