Hey dudes, I can't remember if I've asked this before, but here's the sitch:
I offer GSP and International Priority Express as my two international shipping options.
eBay defaults to GSP, and you can't send an invoice or combine shipping on GSP shipments (or at least I can't figure out how).
How can I guide the buyer to change his shipping method to my alternative so I can send him an invoice for combined shipping?
I hate it when this happens.
