In the UK we offer free shipping but for orders abroad if you place 2 separate orders we will send both together unless we have sent one already. Then we will give you the refund for the postage money not used.
We mainly use Royal Mail for items worldwide but you do have the option to use any courier you wish if you find it more reliable.
This is mainly useful when your national mail service is rubbish. Royal mail items sent internationally will use a countries local mail service. So if you are worried about your items getting to you then choose a cheaper courier option.
For example it can cost only £5 more to get something couriered to you instead of through the national USPS postal service in the USA.
