COMBINED SHIPPING INFO
:
I will be happy to combine shipping with multiple orders. Just let me know so that I can resend a discounted invoice for shipping, and I don't charge anymore than the post office charges me to ship.  So bid with confidence that your items will be combined...please note that as soon as the auction ends,
eBay
automatically sends you an invoice, ignore that one, and wait for me to send you a revised, combined invoice.  If in the unlikely event that you do not receive a revised invoice, just message me and I'll resend the combined invoice, but allow me enough time to package the multiple items safely into their shipping package/box.  Lastly, I can not combine shipping on international orders or through the global shipping program.  I can only offer combined, discounted shipping on domestic orders shipped within the United States. ~
~Thank you again and happy bidding!~
