Postage Prices to Northern Ireland?

Does anyone know if the postage prices to Northern Ireland would be the same the to the UK on the price finder on royalmail. Republic of Ireland had different prices, but I cant find Northern Ireland in the list anywhere. I have a package of 850g to send, but need to know how much it is going to cost... show more Does anyone know if the postage prices to Northern Ireland would be the same the to the UK on the price finder on royalmail.
