FWIW, based on what you have described, a full refund upon return of the goods seems fair. Any deviation from your description on the auction can lead to problems. Certainly, some buyers won't care if there is a slight deviation, but many will and if you were in their shoes, you might too. Seems like a "karma" thing as much as anything else.
