If it says "update" it is usually a free download. They are right on the web-site. Don't forget they have to be done in order (I think). You shouldn't do update #3 if you haven't already performed update #2.
If it says "upgrade" there is a cost for it.
ETA: Don't forget to negotiate the prices for Upgrades too. There is wiggle room.
