If you're dropped off in Calais, you can start hitchhiking at the bottom of the bridge before the check-in. The price is the same for a car, no matter how many passengers (also in Dunkerque). People who booked in advance indicated how many passengers they would have, so it could be better not to mention at the check-in that you're a hitchhiker (?). A one way ticket as a foot passenger is € 40. On the parking lot where everyone's waiting to board the ferry, you can often find another lift that goes in your direction. Just show your sign to all the waiting truckers/cars.  If coming from Zeebrugge note that the truckers usually can have 2 two passengers on the manifest so if you travel this way you don't need to pay for a ferry ticket. Cars usually charge for every passenger on this route, but often from France it's a price per car no matter how many are inside, for example from Calais or Dunkerque. You might be better off hitching with a car, because truck drivers are often more suspicious of people who want to be taken across the channel - their livelihood depends on it, as UK police tend to arrest anybody who knowingly or not help illegal immigrants to enter the UK.
