Thornton's Budgens is ­encouraging shoppers to use the extended Post Office facilities in its Belsize Park store by offering the added incentive of 10% off vouchers.

The London store, which will have a second Post Office counter installed early next month, is giving customers who use the in-store Post Office vouchers that can be used at its deli and fish counters, and on Cook frozen ready meals.

It has also launched a prize draw offering the chance to win products from the in-store deli.

Owner Andrew Thornton said the store had received a grant from Camden Council for the second counter. The counters had been welcomed by customers because unlike those at other c-stores, they were open the same hours as the store until 11pm Monday to Saturday and until 6pm on Sundays.
