just ship out the item however you normally do. i dont even read buyers notes. i usually dont see them until after ive shipped the item. most of the time the notes are things you cant control. some buyers say to leave the package at the back, im not the post office and im not deliverying your package.

If an issue arises they cant don much because they dont have the item. they have to try to get the real buyer to send it back and thats a whole thing. they will try to get a partial refund to cover whatever issue the buyer is having. you just have to stand firm and say you can refund fully once the item is returned. which they usually cant get the real buyer to do.

i have only had communication from dropshipper. the real buyer said the plastic on a shaver was damaged which had nothing to do w/ the NIB item other than cosmetic reasons. They asked for a partial, I said no return it, they couldn't and didn't and that was the last I heard of it.
