I picked up the 2019 edition from Hobby Lobby (with coupon) a couple weeks back. I had skipped 2018. I have the inaugural Mega Red as well as several editions going back to 2010. I don't know why I typically buy the annual edition when one every 5 years would do. On the other hand, the Mega is probably worth picking up annually for the special sections. I mentioned in another thread I probably will when they start focusing on half dollar and dollar coins.
