$100 is high. We bought paperback Stedman Sunday missals for our congregation at $6 each NEW. All the Traditional Mass every day of the week missals are like 40-$50 today.
The Novus Ordo missalettres change every month, would cost more in a short time than the traditoinal missals which last forever. I still use a 1945 Lassance missal.
This is mine. Okay, so it's only $60.
