Nania Car Seat always out of stock

Good Day,<br> <br> I am trying to locate a Nania Car Seat for my baby, however each store that stocks it seems to be OUT OF STOCK and nobody knows when the stock will be arriving. <br> <br> Does Vitality not keep track of how many vouchers that are distributing to ensure there is sufficient chairs and/or is there no other brand that we could buy as I am needing to replace my son's current seat with a bigger one.<br> <br> Thanks<br>
