Do you mean Hannants? They usually list their WNW stock in UK at the same figures as the WNW US$ prices. I can't remember if Hannants charge postage, but they are worth a look if the exchange rate varies after they already have kits in stock.
I almost got a DVa from Hannants a few years back, but even then buying direct from WNW would save about £5. Hannants would be quicker, however there is always the chance that a delivery from WNW may pass by the release fee and VAT. Rare, but it does happen.
