Aras Kargo links up with DHL in Izmir. At least the one in Didim does.
Have used Aras/DHL both to and from the UK.
I did have a minor problem with the DHL site, as had to specify Soke for postcode 09270 as I could not specify Didim.
Package was delayed 24 hours (no big deal) as they tried to deliver in Soke although the Didim address was specified.
I used the Aras Kargo office for the outgoing package.
