Showcase 22 has been a sleeper for a long time. Since the movie has been announced, it has cause demand to exceed supply. As a rule of thumb, when price increases, supply will increase also. If price increased to drastically without any pullback; then this is speculation. But what is considered high, we don't know until more supply comes forward and what prices is established. Even Detective27 didn't expect prices and demand to increase so much. At the end of the day, there is great support for this book now.
