Very nice little shop inside the airport in Madrid.( Aeropuerto de Barajas)
This shop is located in one of the terminals inside the airport, good place to shop before boarding your flight with different types of items for sale such as alcohol and cigarettes but they also have cold beverages and candy.
Everything is tax free and they do ask you for your flight number and the place you are flying to, if you purchase any alcohol they will take it to the flight for you. A bit expensive..I got some gum and candy and spent 3,20 Euros witch is about the equivalent of $3.50 American dollars.
If you are bored and want some reading material they also have that available plus you can kill some time by reading all the labels of all the alcoholic items they sale and just looking around. read more
