In Germany they cost € 1,45 about $ 2,00 at the Rossmann drugstore and that is still almost the double from what a Palmolive shaving stick costs.It's a bit like wine, a very expensive bottle is not always the best. My pick might not be the best for you. For $6, you don't have much to loose. However, so far, between Wilkinson, Tabac and Speick, it's very, very close. I just need to put one above the other at one point.
I personally find the Wilkinson Sword Shaving Stick better then the Palmolive shaving stick, so thats why I don't mind for paying the double.
However Speick shaving stick also doesn't cost more then € 2,50 in Germany and I bought myself one not so long ago.
