Hannants have been selling WNW kits for years. Usually they are priced in UK£ at the same number as WNW charged in US$, so for example a WNW kit originally listed at $79 would have been £79 at Hannants.
When the £/$ exchange rate was higher, even allowing for the VAT and "release" fee for delivery to the UK, it was still cheaper to buy from WNW (and then WETA)
So, now the new Duellist is to be priced on WETA at $189? That means at the exchange rate now ($1.23 = £1) a list price of £153. Add VAT and the approx delivery charge from WETA of £12 (I can't remember exactly) and the total comes to £195.
A pre-order from Hannants is £171.
That's a no brainer, especially as if before the kit is released you then change your mind, you can cancel. Hannants don't tell you when the order is ready as they want the sale, but if you keep checking and change your mind before the kits are released, it is OK.
Of course, the exchange rate could go haywire before the kits are finally released.....
