Our system here at Mountain Warehouse does not treat the Channel Islands a 'UK place of supply' and therefore VAT is not charged at the time of order. The tax is 0.00 and your order is classed as a zero-rated export.
This means the total amount customers from the Channel Islands pay for their order will not change.
We factor in the costs of trading across all of the markets we operate in, and price our products based on a variety of commercial market factors. Thereby, our customers from around the world will experience a single sales price regardless of where they shop with us, although this is subject to minor price differences due to exchange rates.
