Clothes and shoes
Camper shoes can be seen in most cities in the country. While it may seem that they are sold everywhere, finding right model and size may be a trouble--so if you find what you need, don't postpone your purchase. Campers are sold both in standalone branded shops, and as a part of a mix with other brands in local shoe stores. Standalones generally provide wider choice of models and sizes; local stores can help if you need to hunt for a specific model and size.
Besides well-known mass brands which are known around the world Zara, Mango, Bershka, Camper, Desigual, Spain has many designer brands which are more hard to find outside Spain--and may be worth looking for if you shop for designer wear while travelling. Some of these brands include:
Headquartered in Barcelona, has stores in Bilbao, Ibiza, La Coruna, Las Palmas de Gran Canaria, Leon, Madrid, Marbella, Palma de Mallorca, Salamanca, Tenerife.
Designer shoes and sneakers trademark Herman Monster and others for women, men and unisex.
El Corte Ingles
Major national chain that can be found in nearly every city. In most cities, enjoys central location but resides in functional, uninspiring buildings. Has department for everything--but is not good enough for most purposes, except maybe for buying gourmet food and local food specialties. Still very popular with uneducated travelling shoppers - the locals consider it expensive for a department store, though its customer service is well regarded. Tax refund for purchases at El Corte Ingles, unlike most other stores in Spain, can be returned only to a debit/credit card, even if you originally paid in cash. Also, given that they usually occupy very large buildings, Corte Ingles stores are usually a landmark in major Spanish cities and are very well connected to the local mass transit networks.
Private national fashion chain featuring many premium brands. Main location is Bilbao; some stores in San Sebastian and Zaragoza.
Most businesses including most shops, but not restaurants close in the afternoons around 13:30/14:00 and reopen for the evening around 16:30/17:00. Exceptions are large malls or major chain stores.
For most Spaniards, lunch is the main meal of the day and you will find bars and restaurants open during this time. On Saturdays, businesses often do not reopen in the evening and almost everywhere is closed on Sundays. The exception is the month of December, where most shops in Madrid and Barcelona will be open as per on weekdays on Sundays to cash in on the festive season. Also, many public offices and banks do not reopen in the evenings even on weekdays, so if you have any important business to take care of, be sure to check hours of operation.
If you plan to spend whole day shopping in small shops, the following rule of thumb can work: a closed shop should remind it's also time for your own lunch. And when you finish your lunch, some shops will be likely open again.
Spain has the euro € as its sole currency along with 24 other countries that use this common European money. These 24 countries are: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia and Spain official euro members which are all European Union member states as well as Andorra, Kosovo, Monaco, Montenegro, San Marino and the Vatican which use it without having a say in eurozone affairs and without being European Union members. Together, these countries have a population of more than 330 million.
One euro is divided into 100 cents. While each official euro member as well as Monaco, San Marino and Vatican issues its own coins with a unique obverse, the reverse, as well as all bank notes, look the same throughout the eurozone. Every coin is legal tender in any of the eurozone countries.
The euro replaced the Spanish peseta in 2002. A few people may still use the old national currency 166,386 pts = 1 €, 1.000 pts = 6 € and convert into Euros later. This is much due to the huge presence of peseta, and "her" many nicknames in colloquial Spanish.
Cash euro: €500 banknotes are not accepted in many stores--always have alternative banknotes.
Other currencies: Do not expect anybody to accept other types of currency, or to be willing to exchange currency. Exceptions are shops and restaurants at airports. These will generally accept at least US Dollars at a slightly worse exchange rate.
If you wish to exchange money, you can do so at any bank some may require that you have an account there before they will exchange your money, where you can also cash in your traveller's cheques. Currency exchanges, once a common sight, have all but disappeared since the introduction of the Euro. Again, international airports are an exception to this rule; other exception is tourist districts in the large cities Barcelona, Madrid.
Credit cards: Credit cards are well accepted: even in a stall at La Boqueria market in Barcelona, on an average highway gas station in the middle of the country, or in small towns like Alquezar. It's more difficult to find a place where credit card is not accepted in Spain.
Most ATMs will allow you to withdraw money with your credit card, but you'll need to know your card's PIN for that. Most Spanish stores will ask for ID before accepting your credit card. Some stores may not accept a foreign driving license or ID card and you will need to show your passport. This measure is designed to help avoid credit card fraud.
