I will go into very subjective territory but as many do come here for the shopping and gift given too, I will put my favorites over the years in some areas. This is not an exhaustive all inclusive list, it is only my favorites shopping places in Paris proper. Hope you too can make it your own or bring on some more ideas in the comments area.

You have in the Marais area around 4éme or 75004 many interesting boutiques. You have my favorite area the chic 16éme or 75016 with clothing, perfumers,and home decor stores lining up rue de Passy and avenue Victor Hugo. Plenty of ritzy stores in bd St Germain en Prés and surrounding streets. As well as the Department stores like Galeries Lafayette.

If want to get an international wine go to Lavinia, 3-5 bd de la Madeleine, metro Madeleine. Huge place with lots of choices, prices a bit high but hard to get foreign wines available. http://www.lavinia.fr/LaviniaFR/. If you want French wines then head for the Nicolas stores all over Paris; mine favorite is at 3 ave Mozart, 75016; metro Muette line 9 web http://www.nicolas.com/; always friendly service and good prices.
For goodies there are several but my all time favorite is Hediard, probably because I have close to house and use it more;in Paris is at 21 place de la Madeleine, metro Madeleine 75008/ web http://www.hediard.com/?___store=hed01fr.

Again on my roots I always need to look for Spanish and American products and over the years these have been the best price/quality and selection. Thanksgiving, an American store in Paris. Also, a cajun restaurant above floor, run by Louisiana folks. It is in the village St Paul at 20 rue Saint Paul, 75004.Metro St Paul or Pont Marie. Web http://www.thanksgivingparis.com/store.html ;then Cap Hispania, a Spanish grocery store in Paris. This is clean cut and run by Spaniards as well. It is at 23 rue Jouffroy d’Abbans, 75017. Metro Wagram .webpage at http://www.caphispania.fr/
Then there are many market or marchés in Paris, over the years we have settle to go to the Bastille market by bd Richard Lenoir, not only goodies but also the best arts around on Saturdays. The site for the arts is here http://www.artistesparisbastille.fr/ then the local produce was known as the Saint Ambroise, today you get there on bd Richard Lenoir on metro Breguet-Sabin and Richard Lenoir. One of the largest in Paris every Thursdays from 7h to 14h30 and Sundays from 7h to 15h,best. The other is a favorite of my wife , the marché des fleurs Cité at place Louis Lépine, near the Conciergerie. Open Mondays to Saturdays from 8h to 19h Metro Cité.
In closing, these are sites that provide excellent info on stores by arrondissement or else, they are helpful in finding top quality items with current information. There are in French but so its the country,you get the real thing. Hope they help
