We have a constant battle in trying to keep our shipping costs to a minimum.
For UK orders we ship post free.
We charge 15% for shipping with a minimum of £5. The cheapest we are able to send a book to the USA airmail is £9 so we are effectively subsidizing customers to the same extent as UK customers. There is another factor and that is that Mbag (the cheapest rate for books airmail) has a minimum weight requirement of 2kg. This means that on a single book we have to include excess packaging to make up the weight. Alternatively we can add a second book for the same shipping cost. We are therefore offering customers overseas a second title at a 25% discount, post free (the 25% being off the cheaper title). Simply order the first title online and then email us with your choice for the second title and we will send you a Paypal invoice for the difference.
