Heathrow T5 has two stores, one selling Rollies and another an assortment of everything else, Omega included. My question - is it worth buying from those stores? Are the prices there significantly lower than, say, in London?
They have never struck me as much cheaper than what a good hunt about can achieve, the "rrp" or "high street price" is always dubious. Depends where you flying to also as prices abroad can be fortuitous if the exchange rate is right.
