It does not make sense to buy a WNW kit from me in the UK if you live abroad.
I have to pay WNW for the kit - the same price you pay, as delivery is free.
However, we in the UK are hit with a 20% VAT import tax and an £8 handling fee.
If we post to, say, Canada, we also incur shipping costs.
So even to break even, a sale abroad would cost more than that person buying the kit themselves direct from WNW - every time.
I can charge somebody in the UK the full, VAT inclusive cost because that's what they themselves would pay if they bought from WNW, but I'm just adding on extra costs, then postage, if I sell abroad
Non WNW kits may be worth buying as these restrictions are not in place.
