ok, so I shipped a customer 2 pillowcases, and the customer claims that her package came ripped open and retaped and that it only contained one of the pillowcases. :( Does this sound weird to you? Why would someone only steal ONE of the two pillowcases in a package? Would you refund their money or ship them another item free? Any thoughts on how to handle this? I don't have a "shop policy" on this, as I know some people say it is not their responsibility once it leaves their hands. But I am so afraid, if I say, it is not my fault that USPS messed it up, that they will leave negative feedback. This person has bought over 500 items on etsy from other sellers, so they are a frequent shopper.
