A great price for a great car seat.
I was tempted by the Graco Junior Maxi Seat (as posted on this site) and Britax Adventure Seat both on sale at Halfords, but found they only just meet the minimum UK safety standards in tests by Which? and they rated them as "Don't Buys".
The Maxi Cosi Rodi XR exceeded all Which? tests and is a top "Best Buy" seat.
Next best price I could find was £80 at Mothercare.
