I really dunno why they do that.
My realitives just buy that stuff from külföld. They get reklám through the post and I saw memory cards 4-5 times cheaper in Austria (G'day m8). I went to the store and first time in my life I met someone in Austria who can't speak English. I thought oh shite, time to actually use my German for real. But my uncle translated for me.
I wasted 4-5 years of my life learning that shit. I never ever 'needed' it.
