As an alternative to the three Kusadasi markets, there is always Soke which is massive and excellent for buying clothes. Prices are much cheaper. Soke market is on Wednesday.
Soke is easily reached by dolmus - you already know the dolmus station. Takes about 40 minutes each way.
Selcuk is superb for food shopping - not so hot on the clothes side though. Apart from the market there is a lot of small restaurants and bars that still have that Turkish charm and its a nice day out combined with the market. This one is on Saturday.... and of course its just up the road from Ephesus and the other direction the famous wine making village, Sirince.
