I combine shipping for customers who buy multiple items, this is not automatic. To have your items combined just end the listings but do not send payment. When you are done shopping then email me for a combined invoice which I will promptly send with the adjusted shipping fee. Most domestically shipped items are shipped insured Priority Mail with the exception of items weighing excessive amounts. Books will be mailed by Media Mail. I ship Internationally via eBay's Global Shipping program. Using eBay's Global Shipping program means that eBay will be deciding your shipping fees and I will not be able to send or edit your invoice but I will be packing & mailing your order. I Do NOT Accept Returns. Please make sure to review all measurements stated in the listings and to shop with a caliper & measuring tape handy so you will not be surprised by an item's size when you receive it.
