As soon as you confirm the order you get an automatic reply, giving the relevant payment details. If not, check your spamfilter-folder. After receiving your payment the parcel is mailed to you. You get a confirmation of shipment via email as well, with the tracking number if you had chosen insured delivery. So the principle is "you pay, we mail".
Please note: due to a fault placing your order via Firefox may not work. You can send me a screenshot of your basket (info AT tolkienshop DOT com) or order via a different browser.
