Post Office customers are being wrongly advised to choose a £6 recorded delivery service when a £1.50 alternative would be equally as good, a consumer group has found.
A mystery shopper survey of Britain's 870 high street Post Offices by Consumer Focus found that seven in ten shoppers are offered more expensive delivery options than they require when they post a letter.
As part of the survey, the 'shoppers' posted a letter that needed a signature on arrival but was not urgent and did not have valuable contents.
According to Consumer Focus, the most appropriate delivery option in this case is so-called Second Class Recorded Signed For delivery, where costs start at £1.45 per item.
However in 69 per cent of cases, the mystery shoppers were offered the more expensive Special Delivery option – where prices start at £5.90 – or the First Class Recorded option – where prices start at £1.55.
