Two quick things:
1) What are the requirements for a car-seat in Singapore? I know it's allowed to hold your kid in a taxi. What about a private car? I've heard directly contradicting things on this from locals, and haven't had a ton of luck searching. Although I will get a car seat either way... Just want to know. (Anyone from the US remember those "Click! I'll be your safetybelt!" commercials?

2) What's the best place to get a good price on a car seat I'd actually trust to put my kid in? Kaki Bukit area? The wife and I found an acceptable looking one for $199 at the store in PP across from Mothercare, and one that was almost identical was ~$320 at Mothercare. Is that a decent price, 50% less than Mothercare, or could we expect even less at KB?
