Food / Can you buy Virginian tobacco in katowice or poznan? [3]

hi
we are once again visiting Poland in our caravan
going to Katowice to visit my wifes relatives,
then off up to boskowo to go fishing.

does anyone know if i can buy golden virginian tobacco in either katowice or poznan
if so how much does it cost
also is it best to bring english money or the euro money to swap for zloty
many thanks
