is there a duty free shop near to the port
There are no "Duty Free" shops in Europe anymore - they all have to tax goods at their country's going rate. The only exception is when you can reclaim the tax as a non EU resident.
If however you are looking for excellent value for money wine then look no further than the Roscoff Wine Seller on the industrial estate just up from the port, heading into town. They specialise in direct from the producer wines and always have great stuff at very good prices.
