To combine shipping for multiple items, please use the ebay Shopping Cart. Simply add each item you like to the cart, and after finished adding ALL items, its nice and easy to pay from the cart in one go. Shipping automatically combines at checkout and is based mostly on weight of the items, plus packing and insurance costs. You can also click "request total from seller" and we will send invoice with shipping discounts as possible. Thank you for helping us lower shipping costs, and save on the environment too..
