Britax 9months to 4 years car seat. Stage 2, £45 in-store
Not an isofix one but the seat belt secure type.
Sorry forgot which model it actually is (will try and find out and update later, it might be freeway) but a super price for a stage 2 car seat, cheapest on the mothercare website is £75.
Not sure how long this deals on, may be linked to baby event till 27th.
There was about 6 on the shelf in the Leamington Store.
