But.... there is more! France, as do most European countries, abounds in Festivals, Fetes, and various fairs that are equally social and shopping opportunities. In Paris, watch for signs for regional festivals where a particular region of France will show off its food and culture for a weekend or a few weekdays. Watch for 'Brocantes' which are temporary markets for nearly antique items from rugs to furniture to books to pottery and china, plus many other choices. These are typically frequented by Parisians and a few savvy visitors. A 'Braderie' is a rummage sale which is likely a spontaneous event not run by professional sellers. In all cases (except the regional festivals) it is fine to politely request a 'petite remise' or a discount, especially if you are buying expensive items or numerous items.
Paris is a moveable feast, fete, foire and always fun!
