Amazon UK is celebrating claiming number one spot for customer satisfaction with a £10 promo code - but it's only valid until midnight tonight.

The UK Customer Satisfaction Index (UKCSI), run by the Institute of Customer Service, has given Amazon UK top dog status following a survey of 10,000 customers.

We'd forgive you for not being overly concerned with that information but Amazon's celebratory £10 off promo code may be of more interest.
