Skechers Women's Go Walk 4's in size 7 (I think a size 5 was around this price aswell at the time of posting) £13.47 using the code "BABY25" when you create an Amazon baby wishlist! Bargain. When I tried it the code would not apply but a quick online chat with Amazon rectified this. She confirmed that it definitely was an eligible item and refunded the discount.
