Why's Efke so much more expensive than Foma?

Shopping Freestyle, I've noticed that Efke is $1 more than Foma in 120. That's not huge money, but it makes a difference if you're buying up some stash.

Just curious if anybody knows some practical reasons why? I don't know tons about the economic conditions in the Czech Republic and Croatia, but it seems like they shouldn't be that wildly different. Does the Efke factory just not churn out as much?

Supply and demand? Cost of production? Those seem the most likely reasons to me.
