Homemade Sausage Making

I was just on a Polish site that sells sausage making supplies and they list a full hank 28-32mm hog casings for 30.00 zloty that's $9.56 in US. I checked the sausage makers web site and the same casings cost $39.99 US that would be 124.00 zloty. Why such a difference.

Well, maybe they are already stuffed ?
But , check ebay, for example:
