Hi, i'm not too sure about the price selling here in malaysia....
Is the VAT included in this price? Are you able to get the VAT refund? Is the AD there willing to give you some discount?
Malaysia has no tax and usually 18% for TAG can be given (some can get more depend how close you are with the AD)...
I was in UK for long and I've never buy any watches there (except used from those well known forum) simple because of the VAT and I can get it cheaper in Malaysia

If you will be back to UK after your trip home next month, maybe can do a price compare before you decide

I can understand how suffer it is for the "waiting game"

Good Luck

Scott
