Hey guys

I have never used a/s astringents moisturizers (or even lather) before I started wetshaving. Since then I have tried witch hazel and am loving the effects and plan on adding a alum block and a/s to the mix.

My question is this, I have seen alum blocks priced anywhere from $4 to $24. Is there any difference in them or am I just paying for the brand? Are there any brands to avoid or certain ingredients (besides alum-har har) to look for?

thanks guys!

Also anyone know where I can get some osage rub in southern california?
