I recently received unfair and unjustified negative feedback from a buyer for not reducing the postage on 2 paintings he purchased. He did not request this and while I normally do reduce postal charges for more than one painting purchased sometimes the cost varies depending on the weight and size of the parcel. This A4 size painting is very near the limit of a large letter and can go over and into the size of a small parcel which costs twice that of a large letter.
