If you purchase more than one item, you will only pay postage on the first one, all the others will be free of postage.
Postage Information:
I post all of my items by Recorded Delivery (Signed For). This is to protect both parties with a secure delivery service, that includes compensation cover in the event that The Royal Mail lose or damage the item.
Of course this will make my postage charges higher than sellers that do not offer this service, but I do give postage discounts on multi buys (see above).
