Sorry this is a bit of a rant.
I asked a seller recently how much postage would be for a dress I was watching.
I live in northern ireland.
Her reply was that she only posted to the uk!
I am sorry but northern Ireland is part of the uk ( politics - aside). Our mail is delivered by royal mail and should not cost extra!!! It may take slightly longer but royal mail special delivery still arrives the next day. Normal services are generally good too.
In future could I ask all sellers that a BT postcode is in the uk and not to charge more or be ignorant and see the word Ireland and think it is part of a different country.
Rant over
It really is a bug bear of mine.
