D, I am pretty much with you. I personally am much too lazy to go to bat on refunds unless something is really egregious (ie; total non-delivery), but I have - once, in the context of hundreds of FO's - experienced something that I knew was really wrong.
I guess I think it is good to try to let the company know if you *really* know something is wrong. Not the "I don't like this scent and I don't think it matches your description" thing, which seems to be the case with the OP. But surely there must be a case in which FO sellers make mistakes and should refund when so?
Different context, but soaping suppliers, even reputable ones, sometimes make mistakes, eg. the ED lye brouhaha. IMO, they should have just said "it appears some of our lye batches w/ batch numbers ___ to ___ might be problematic, if you have received an order that fits within those parameters and are not happy with it, we will provide you with a refund/credit." I think their failure to do that was a great mistake on their part.
I know this is not the same thing, and I may be wandering too far afield, though.
