I do a calendar every year and when I bulk print, I use
https://www.printingcenterusa.com/. I print over 10 and they run about $6 each, spiral bound. I ordered 20 this year because I got a break on the price, then realized that I only needed 10, I had just got over-excited about the price break lol. My friend orders 22 every year.
I scrap the top half using photoshop, then use Photo Calendar Creator to make my calendar and upload it in PDF format to the print center. The advantage of using the calendar program is that I keep the birthdays and anniversaries in the calendar program, along with the current year holidays. I can customize everything and keep it up to date every year, adding new babies, etc. We have created a family calendar every year for the last 7 or 8 years and the family always looks forward to it.
Here is my family calendar:
