Chewbacca, forward thinking soul that he is, has already started prepping the cargo to be moved. Now that the Millenium Falcon is on terra firma (or what passes for it on Jakku, anyway) the three of them can go find their contact and start making the exchange.

The only exchange there is among spacers like this crew; money for cargo.

All goes well for a change. All the money that was promised, by the exact people who were supposed to be meeting them there. Han, Rey and Chewie get to hauling those vaporators and though they're heavy, that goes as expected too.
