From their website:
I’m happy to announce that we’ve added new shipping option – fast, trackable courier. At the moment it works only for EU, but soon I’ll try to make it available for the rest of the world.
Of course cheap, regular shipping can still be chosen. And I’m even more happy to say it got improved. We’ve signed a contract with Postal Services of Poland and they’re handled slightly different. I’ve been monitoring delivery times for the past 3 weeks and they reach the destination faster.
