The ebay system is not combining postage, if you order multiple items, please wait for me to send a combined invoice, before paying, to avoid being charged multiple postage. All items are posted promptly once payment has cleared, however australia post is very unpredictable with delivery times, if you require your items to arrive within 2 weeks (Australia wide), or you require your item to be trackable, please use the express post option available on all listings. If you cannot see it please email and request an invoice with express post before paying, thanks. If regular postage is selected I cannot be responsible for items arriving late or being lost in the post, as this is something I cannot control, thanks.
