Something Mum & I had been looking forward to the most on our trip was exploring real Parisian flea markets - we just don't really have proper flea markets in Australia. Saint-Ouen is said to be Europe's largest flea market, although it could be more accurately described as an entire suburb of different markets. Most deal in antique furniture, but there are plenty of other bits and bobs to be found around the place. I think Marche Vernaison is the most interesting, as it is very old, semi-open air and made up of endless narrow alleyways filled with all sorts of treasures - it has the most variety. We spent a whopping seven hours exploring the area, although if it hadn't have been so hot we probably would have stayed longer. It's definitely a must-see for any market-lovers heading to Paris! There's some useful information here, here, and here.
