I would just leave a generic feedback, not negative and probably not neutral since she did try to make things right. No, I would not have shipped first, but then she did refund the difference. You always have the right to send the item back for a refund if you want, but just give a good generic response. It is very hard to sell on the auctions and nothing is so irriating as a negative or neutral feedback. I'd rather not get one at all!
