I have to agree with Adam. If you are new to Didim, well ok, then you ask the question.
If you are not, you have an apartment here or you come here regularly on holiday, then what do you do when you are here??
Don't you go to any shops?? Do you just go to the beach, then to the bars and that's it!!
If you can spare some of your time to go and look round the shops when in Didim, then you will have answered you own question??
Why do you ask other people to do your shopping for you??
