You don’t necessarily need any advice on which shop is best as they display their products where you can take a good look, feel the material and try. Stroll into the village where all the shops are on several streets.
There is no obligation to purchase a product when you enter a shop and a drink is offered; it is in Turkish Tradition to Serve and Host the Customer most pleasantly.
You can haggle if you believe that the item is not worth the price you have had in your mind. But, once you agree to an amount, it is rude not to purchase.
In the shops of Sarigerme, you can find all kinds of Shoes, Clothes, Sunglasses, Boots, Caps, and Jeans, not necessarily at the lowest price, but excellent stuff for men, kids and women.
Just be aware EVERYTHING is fake. There is nothing original. Providing documentation for its being genuine is part of the imitation game. This does not mean less quality, especially in clothing and bags. However, when it comes to Jewellery and watches, raise your warning sign bar as high as possible.
If you can not find what you are looking for in Sarigerme, nearby towns such as Dalaman and Ortaca, Marmaris, with more shops, might be worth visiting, especially for extensive bargain shopping.
