I have just had an order for Jersey, but the postage rate the buyer was charged was the one that I use for Rest of World destinations.
I have looked at my Postage Policy for the weight, and nowhere can I see why this should be happening.
The Guernsey postage rate is correct (same as rest of UK)
I checked a couple of different sellers and it's the same for them - Guernsey rate the same as UK, Jersey rate was the International Tracked price.
I am guessing this is an eBay error?
