Rates based on the price per gram of 9 carat gold quoted on the websites of H.Samuel (hsamuelbuying.co.uk) and H&T Pawnbrokers (harveyandthompson.com) on 30/12/2010. * Offer is valid for consumer transactions only before January 31st 2011 (excludes business or commercial exchanges). ** Postgoldforcash.com (recommended partner of WHSmith) has no price calculator on their website so the price quoted is based on the payment received from selling 12.75 grams of 9 carat gold on 30/12/2010. The comparison was made on postal services.
