Each maker has their own shipping policy and rates. These will be detailed on their product page. It will also be shown once you have added your items to the basket, before you make your payment.
Where you are buying various items from various different makers in one transaction, you will be charged a flat shipping fee of £10 and this fee will be payable in place of the individual shipping rates listed by each maker.
Makers vary in the destinations they will ship to. Some makers only send to the UK and Ireland, others will send items to the EU and other International destinations. It is up to you to check that the maker posts to your location before you make your purchase.
