Aspen Specialist Media (0171 262 2622), in partnership with Actmedia of the US, has launched an in-store coupon dispenser. The system is claimed to have increased product sales by up to 32% in the States and is currently being rolled-out in the UK by J Sainsbury following successful trials. Sited at the point of purchase, the device prints-out a coupon which consumers redeem at the checkout, having bought a qualifying product. Actmedia claims that 70% of all US households use its in-store marketing products.
