I found this and was really pleased!! As I bought 4 car seats, my order was over £150 and I had free delivery.
The Evolva 2-3 product description
Made with exclusive fabric, the Evolva 23 is deep with softly padded side wings for optimum side impact protection - a great choice!
* Car seat suitable from 15kg/33lbs to 36kg/79lbs (from approx. 4-11yrs)
* Child faces forwards in a seat secured with the adult seat belt
* Deep, softly padded side wings for optimum side-impact protection
* 11-position adjustable headrest
* Belt guides to position the adult seat belt correctly
* Includes pull-out drink and snack holders
* Removable, machine washable cover with protective anti-bacterial finish
My quidco tracked immediately and I used the code EM8 for 20% off. This reduced the seat to @£36 with possible quidco making it @£33 + postage. (You could always buy more, get free postage then return the extra to store.....of course I wouldn't do this!!!)
Without quidco, it's still a good price delivered. (£41) Thanks to Flake99 for being nice!
Also purchased the Evolva 1-2-3 which is priced £99, with code and quidco, @£74.
Can always be returned to store, or taken to store for a fit check!
