A scheme is being launched to encourage people to shop more in Ilkeston and Long Eaton.
The Shop Nearbuy loyalty card is being launched this weekend to counter out-of-town shopping centres.
Shoppers will be able to get loyalty card passports stamped when they buy goods worth more than £2.50.
Once 15 stamps have been collected, the shopper can enter a monthly competition for prizes worth up to £60.
The passports are available at 130 outlets.
The scheme, supported by Derbyshire County Council and Erewash Borough Council, starts in Ilkeston on Saturday and Long Eaton a week later.
Coun Geoff Smith, Erewash’s lead member for planning and regeneration, said: “This scheme will bring benefits to shopkeepers and market stall holders and shoppers alike by encouraging a strong customer base.”
