Postage & Shipping Our postal charges are automatically set and are based on the average weight of books. If the actual weight of the book is less, then we will reduce the price charged accordingly. If the weight is slightly greater then we will absorb the extra cost. If however the book or set of books is greatly in excess of the set rate, we will notify you by email and proceed with the order when you have confirmed acceptance. Please note that estimates of shipping times are estimates only which have been given by Royal Mail or Parcel Force. Actual arrival times may vary. Refunds Returns may be made if books are found not to be as described and a full refund given. Returns for other reasons will be dealt with on a case by case basis.
