Had look at a few of their items that match stuff I'm planning to buy and its interesting.
They do the Argyll jacket for £80, but for £80 Geoffrey also include carrier, sgian dubh, choice of sporran, chains and Saltire kilt pin.
Prince Charlie jacket, £85, but for £90 Geoffrey also include carrier, sgian dubh, choice of sporran and chains and Saltire kilt pin.
So it shows its worth shopping around a bit to get the best price.
As regards duty etc., when I got my brogues from Geoffrey, which were superb quality, I didn’t have to pay anything extra.
