For combined shipping on multiple items:
Using the full version of the site (not the mobile app), add the items you would like to your cart and then pick "request total from seller" instead of "proceed to checkout". Follow the prompts to request an invoice. Please wait for the invoice to pay.
***Please note - At this time, I am not able to issue partial refunds for shipping. To receive a new total, please follow the instructions above. I apologize for the inconvenience.***
