I just ordered mine for our small Burns Supper this Saturday night. We are lucky in that we are able to get it all year round, made by a local Scottish butcher. They keep some in the freezer to saw off a slice if you don't want a whole haggis. There is also another Scottish fellow in town who makes up large quantities for one of the grocery store chains this time of year as well.
I really like it. It's great for breakfast as well as dinner. My wife and I tried the stuffed chicken recipe, and we won't make it again. We like our haggis naked!
