Neos Marmaras Market is open on Thursdays and it's located near the port, near the sea, on the opposite side in relation to the local beach. Market is not too big, but it's sufficient to provide all that is needed.
Here you can find olive oil, olives, honey products, spices, homemade teas, meat, fresh fish, but also clothes, shoes, souvenirs, bags, curtains, bed linen...
The prices are lower than in supermarkets and shops, fish is also more favorable than in fish markets. Market is open from 10 to 14h, so if you have free time, walk around at least once during their stay in Marmaras and supply with local products on it.
