The website is adding postage charges onto digital products for no apparent reason. If you do buy something and it adds postage where it shouldn't (there should never be a postage charge for a digital product) I will refund the postage charge as soon as I can. You don't need to let me know, but if you are worried I've missed it then please feel free to email me: firstname.lastname@example.org
The technical people are looking into this, and I'm hoping for a fix sooner rather than later.
Thank you so much for your patience and understanding!
