I am going to Marrakech shortly and would like to buy some Morrocan slippers. However, I have heard that in Marrakesh the prices are considerably higher than those in say Fez. I know I will need to haggle and I am sure the retailer will be very adept at this. I would like to give them a fair price so that it is a win win solution. Do you have any suggestions as to where to buy and what to expect to pay?
