The Whiskey Exchange

I'n in the UK and use them regularly. They are very solid and they ship worldwide. Master of Malt better though and usually slightly cheaper.

@crystalb1 There was a discussion thread titled Anyone in the US used The Whisky Exchange?, this had quite a few responses which you may find helpful if you are from that side of the pond.

I doubt too much has changed other than the USD to GBP exchange rate getting quite a bit better in the last few years...
