Signet Group jewellers Ernest Jones and H Samuel have demonstrated a unique retail promotion drive for jewellery this coming Valentine season, launching pop-up stores in London train stations, reports say. A store named ‘Little Store of Love’ has been launched by H Samuel at Waterloo station and Ernest Jones’ offering is a ‘Love Boutique’ store at Paddington. %% The stores aim at enticing the customer ‘on the move’ with convenience of purchase, when one is too busy to visit a high street store, and for the ‘last minute shoppers’. The jewellery being offered at the store ranges within £10 to £200. The company reports that the pop-up stores compliment its national store and ecommerce offers, reports add.
