Share 'Salon du Chocolat - Paris 2010'

I am off to Paris in a few days to attend the Salon du Chocolat.  I have a question for those of you in the know.  Can I purchase chocolates at the Salon?  Or is it like the Fancy Food Show where no purchases are allowed?  I am assuming - because the show is open to the public - that sales are a big factor in the event.
