Do you think the same is true for currency fluctuations? Just not worth the trouble or simple enough to add a sticker, like some stores did to hike the price in the states?
I'll post a run of Astonishing Tales from the UK that I have. The price goes from 8p to 10p and then back down to 9p. So there was actually a price drop from one month to the next not the most common thing in the world especially in the 70's.
Thats what made me wonder. Since you could have a price drop with the US 30 cent variants compared to a 25 cent issue the next month.
Still, I think you're right, it wouldn't be worth the effort in the end to vary the printing for such a small market.
