In Britain, for years, there was slogan than many banded around, "Rip off Britain". Prices were compared to those in the US and more importantly, in France/Western Europe.
However, it was purely down to the UK having a very strong currency for years, it was over 2 US$ to the UK Pound for years and years. Once the banking crises hit, the pound was hit hard and ever since then we have been the country to buy from. Electrical and Electronics have been cheaper her than anywhere for several years now. It probably cost 30% more in France now.
However, it is starting to creep back up. It is already over 1.6 US to the pound and seems to be trending that way, so, buy them while they are cheap.
I have to agree about the point made in terms of, if it is the best, what you want and you can afford it, buy it... I only buy what I want, never because there is a deal or a sale/bargain. If I want it and can afford it I buy it.
