Okay, firstly – Royal Mail has increased prices across the board – we use second class tracked in the UK – this has gone up about 5% and then we use International Standard for the EU – which has also gone up 5%
For everywhere else we use International Tracked – which, in the case of the USA and Australia/New Zealand has increased 10%,
BREXIT – obviously nothing will change for the rest of the world postage – but for the EU we’re now treated like your importing from the US – so please check what costs you might have to pay at customs. HOWEVER if your package is under 22 Euros until July 1st there are no duties. so single tees will never be taxed at present..
