Foodies, help! What's the difference between Fusilli Bucati and Fusilli?

[missorinoco]

Doing my food shop.
Fusilli Bucati is cheaper than Fusilli but as far as I can see from Google the only difference is the hole through the centre of it. What am I missing. It's not the money, I am now curious!

It's longer than normal fusilli and better for picking up chunkier sauces (eg ones with meat in them.) It's really more like a noodle or other long pastas (like spaghetti.)

Thanks.
