Just thought I would pop in and mention that we got a S n S Meridian car seat - it was around $300 - great car seat. A few months later friends of ours had a baby and she showed me their Fisher Price seat that was from Kfart for $170 on sale and it is the same seat. Different fabric and label obviously but everything else is identical.
It's worth doing some research to find out which companies make the products you are looking at bcos you can buy the same product under their cheaper brand. I remember in my years at the old mart that the "cheap" brands used to come in the "expensive branded bulk packaging.

Good point Tan!
