Vtg Sears 78 Adding Machine Model No. 603-58440 parts only comes on

Description

Buy 3 get 1 free requires all items to be full price.
I do combine shipping on items just let me know or request an invoice.  if discounting prior to sale isn't possible i can refund after payment.  example:  if you send offers or i send offers and they are accepted, ebay considers this a discount and will not allow you to request an invoice.
If global shipping is the available option and you would like combined shipping we will have to switch to international shipping.
Ebay will not allow sellers to change the shipping cost on global.
If you have any questions please feel free to send me a message.
