Tangier
If you are going to buy in the medina of Tangier I recommend avoiding the main streets, and I suggest you go in adjacent streets offer interesting and authentic things where locals shop as well. On the main streets they will surely offer you low quality items aimed at unsuspecting tourists at rather high prices. If you want to get slippers, teapots, fabric or you want to dig for a good price and compare prices you have to become an expert in the art of haggling. My advice is not to appear to be too excited when you see a garment or object you like, and do not believe everything they tell you, as they usually have a enviable persuasiveness.
