Mariahilferstraße looking toward the district Mariahilf
Store hours are generally 8 or 9AM-6 or 7PM Monday-Friday, 9AM-6PM Saturday, Closed Sunday. There are slightly longer hours at some malls. Credit cards are normally accepted at large and at high-end stores. All chains that you can find in the malls also have stores on the city's shopping streets, which tend to be more accessible and tourist-friendly. Flea markets are usually can be found on Sundays, where one can buy items at very reasonable prices.
There are 21 markets with stands and small characteristically Viennese hut-like shops that are open daily . Additionally many of these have true farmers' markets, often on Saturday mornings. There is a large variety of sellers and markets, from the upscale to the dirt cheap. Each has several shops of different kinds (butcher, bakery, produce, coffee, etc.). There is another handful of weekly farmers markets around the city as well as seasonal markets like the Christmas Markets.
Open from Nov 15s or 20s to Dec 23th or 24th, most Viennese Christmas Markets are not so much for shopping as for eating and drinking. From midday until the late hours of the night, people gather at Christmas markets to drink mulled wine, punch, and chat to one another and the occasional stranger. Entry to all of these markets is free.
Rathaus. More of a fairground than a Christmas market, this is Vienna's largest and busiest incarnation. Located on the large town square between Rathaus and Burgtheater, the Wiener Christkindlmarkt is by far the largest and probably best known Christmas market in Vienna. Large Christmas tree in front of the townhall, skating possibility, adorned trees in the park, often crowded!
Spittelberg. Probably the most delightful, though often quite packed Christmas market in Vienna, the Spittelberg market is scattered over a series of lanes lined with picturesque early 19th century Biedermeier houses (many of them former brothels, which is the reason the area was spared early 20th century urban renewal). Some of the stalls are extensions of the shops and bars of this normally rather sleepy area.
Maria-Theresien-Platz. A relatively new market between the two museums and en route to/from the MuseumsQuartier (MQ). It is easy to maneuver than some and the quality of the goods is better than most.
Schönbrunn. One of the better markets with higher quality goods and a more festive atmosphere in front of Schönbrunn palace. It is easier to spread out here and the specialties are food, handmade soaps, and candles.
Belvedere. Another recent addition to the city's Christmas markets, the market in front of the Belvedere palace is spacious and emphasizes the homespun.
Resselpark/Karlsplatz - A small, alternative and more rambunctious Christmas market in front of Karlskirche.
Freyung. A fine market in the First District frequented by locals and professionals on their lunch break and downtown shoppers. Focus on handicrafts and original gifts such as hand-made Christmas decorations, mangers or objects made of natural materials. Christmas cakes and biscuits as well as hot punch and Glühwein. There are usually fewer tourists.
Further afield a famous and overly bustling Christmas market may be found at Grafenegg castle. Entry is €7, children under the age of 12 are free.
Charity auctions are common in Vienna. Some stores give their proceeds to social programmes .
International Festival Charity Bazaar. Taking place in 2013 on November 30 at the Austria Center U1 – Station Kaisermühlen, has been organized yearly for over 40 years by the ladies of the United Nations Women’s Guild of Vienna. Volunteers, from a 100 different countries, who have some kind of connection to the United Nations, organize it and all proceeds from the Bazaar go to children’s charities in Austria and around the world.
Viennese supermarkets are not very large, especially compared with the hypermarkets covering the rest of Central Europe. However, there is practically one on every corner. They are open about 7AM to 7PM M-F and 7AM to 6PM on Saturday. Later, on Sunday and on public holidays, few stores are open: three in train stations three at the airport (to 11PM) and one at the General Hospital (Allgemeines Krankenhaus, AKH). Hofer, Penny, and Lidl strive to be discount stores, whereas Billa, Spar and Zielpunkt as well as the larger Merkur tout selection and quality. There is not a major difference in prices. Most regular stores have a deli where the clerks make sandwiches for the cost of the ingredients you select. Although many products are Austrian none of the chains are actually Austrian-owned. If you want to support the local economy more you can do so by frequenting independent shops or visiting actual markets.
Upscale grocers are not common in Vienna.
