Do they sell Swedish potato sausage?

It's a German store owned by a German family. Try it!

Didn't see that last week when we went it's more German and Hungarian styles of sausage

Not sure. Call, they have dozens of different types

No

never seen it there before. they do make their own Italian sausage and Irish bangers so not outside the realm of possibilities that they would make something Scandanavian.

don't think so
