I ordered some DOM from Gammagoblin, so I FE'd. Anyway I looked at the details and it said "combined shipping" next to shipping. I messaged the vendor about it, but are they able to do anything about it, or am I fucked? I don't even know how that option got chosen.
They'll most likely cancel the order and make you redo it. As long as you tell you them it was an accident, they will understand and not blacklist you.
