When purchasing more then one item,please just add to
a shopping cart,they will be combined for shipping and savings will be refunded to you (USA and CANADA ONLY).
Alternatively,you can contact us for a  shipping quote before doing so , or an invoice can be sent to you. 
 For International (out of a  North America) shipping,there is no saving in combining as a shipping fee increases substantially after weight of the package goes over
0.5 Kg and will be shipped separately. If you wish to have your item combine anyway,please contact for a shipping quote.
