As an afterthought, if you have a particular make and model in mind you could try putting it into the search bar on Scrooge
. It would allow you to compare if it is cheaper to buy in the UK and ship or buy here. It would also allow you to decide how the price you are being asked compares with other Greek outlets.
For example, if you put Kamisiana's Scott Scale 940 into Scrooge you get only one supplier listed for Greece, Action Bikes
in Athens. They have it on offer at the moment for €1,929 reduced from €1,999. Pedal on are offering the same bike for £1,729. If you add £100 for transport with Nomad and convert to Euro at today's exchange rate it would be €2,059. In this case more expensive to ship from the UK but in other cases it might be cheaper.
As another example Antonis in Chania is offering an IDEAL BOOMMAX 27.5 2017 at €899. That is also the best price Scrooge has, at Action Bikes again, and Ideal bikes in the UK has it at £890 so again dearer in the UK.
