Gold - Dubai or Kuala Lumpur (KL might be out of date )
Spectacles - Paphos Cyprus
Diamonds - I would think India or Israel ( if you know where to look ) Although again Paphos is a lot cheaper than the UK.
Electronic goods - Singapore from a main store if you want it shipped and guaranteed to work
Mobile phones - Found nowhere cheaper than Dubai yet with the same provisos as above.
