To celebrate the Queen’s Diamond Jubilee, William & Son has teamed up with fellow Royal Warrant holder, TABASCO® Pepper Sauce . 600,000 limited edition sauce packs have been decked out in red, white and blue and offer the chance to win a one carat round brilliant diamond, set by William & Son and worth £15,000, with every purchase. They will be on-shelf at leading supermarkets and independents across the UK from the beginning of May and will be available for 6 weeks, throughout the Jubilee celebrations. Open your bottle carefully, and if it has a special white insert under the cap you’re the lucky winner.
