Ahhhh... makes sense. Thanks OP! You saved me a few quid as wife has been on at me about replacing the existing one as the buckle broke. One min I am driving, next minute, my son has done a houdini on the car seat and is climbing on the handbrake on the M25!
It will work for you as you spent over thirty pounds,previously it was working on anything,there was no minimum spend.
I just bought a black ferrari 123 car seat for 60 and stuck this code in and it went down to 55. Free delivery over 50 quid too. Bought at 10.57am Fri 29th July 2016. So code still working as of a few mins ago.
Great spot OP. Code not working now.
