Normally suppliers handles it as the volume of import to UK was large but now sending parcel to Eu will be smaller. In one shipment, we can send 1-2 boxes ( i think it was up to 30-35kg) without customs from Turkey to Eu. So someone can take the boxes to PTT post office or use another transport company to come and collect and they can delivery without requiring any custom declaration. I got a quo for 20-25kg box 70Eur from Istanbul to Germany with collection. PTT might be cheaper as they dont do collection, you have to take boxes to them. I havent got a quo for that yet.
