The Maxi Cosi CabrioFix is possibly the most popular 0+ car seat going but the rather handy ISOFIX base costs more than the seat!!
Been looking around for a while and whilst in John Lewis in Cribs Causeway (Bristol) noticed them priced on the shelf at £78, asked them to check as even they didn't think that was right.. turns out it's being sold within range of that store for that price so they match it on the shelf.
Being sold at Tesco Direct for £78.29 so should be available at most John Lewis at £78.
To confirm, this is the ISOFIX base EasyFix, not the non-ISOFIX EasyBase.
