You will struggle I'm afraid to get something decent , Tekzen do have them but not the best of quality and size. We ended up just driving to Antalya and went to Koctas (B&Q) in the Ozdilek shopping centre and got real good quality Keter Storage boxes , approx 150 lira each but serves there purpose, check the Koctas website, saying that it certainly cost more for the other shopping with it being a Shopping Centre , advice, don't take the Wife....
