Chicco keyfit

I'm looking at getting a chicco carseat and stroller. Our local walmart carries a chicco travel system but it only comes in one colour (lime green) so I was going to order off the chicco website but I've noticed the website doesn't sell travel systems. You have to buy the stroller and carseat/carrier separately. Is there anywhere I can buy them together in different styles and colours? And anyone who uses chicco products, what have your experiences been?
