Recaro Isofix base currently has an extra 10% off on the Halfords website. You can reserve online & pick up at a local store or have it delivered. I have just collected mine from the Stockton store. These are 85 pounds on the Mothercare site.
I have been looking for one of these on offer for months. This is a real bargain, just try finding a cheaper one online !
With a Recaro Isofix base, you do not need to buy a further base when you get the next size up seat. Unlike the likes of Maxi Cosi, who use two separate bases for some of their seats.
**** Please be aware that I cannot find an expiry date for the offer, so I have put it up as a week, but it could be longer or shorter than that, sorry :(
