The Nuna Pipa car seat is $100 off MSRP on various sellers online. I personally have it and I love it a lot. It's super light weight and easy to take baby in and out of the car without waking baby up. Bottom line, infant car seat is a MUST unless you plan to keep the infants indoor all the time.
You can google search for the coupons and cash back sites for the following sellers to maximize savings. For example, you can sign up neiman marcus newsletter for 15% off. Neman Marcus also offers free shipping and free returns.
