Until last Sunday, Sainsbury's shoppers using the old Reward Card had to spend £1,000 to earn enough vouchers for a ticket to Legoland. But using Nectar, they would have to spend £1,500. The amount spent in-store to get two Odeon cinema tickets used to be £750 but now it is £1,000. Similarly, a bmi flight to Amsterdam would have cost the equivalent of £2,500-worth of shopping but now customers must fork out £3,000.
