If you haven't checked out Discount Shopping at the Best Deals - NoBetterDeal.com for baby stuff I highly recommended it. Last weekend I was able to order our stroller and carseat off from that site for the same price as just buying the stroller. Today I ordered the swing and the price was $50 cheaper then Amazon. All of the things are way more expensive on at Target too, which is my other go to baby place.
Overall I've saved about $200! Ideally it would be cheaper to buy used, but I went to all of the consignment stores in the area last weekend and I couldn't believe how used everything looked. The carseats and strollers that they were selling were not that much cheaper then what I paid for things off from nowbetterdeal, and they looked older and more beat up then the strollers and carseats that my girls have been using for 5+ years!
The swing that I bought today was the same price as the comparable used swings that I was looking at last weekend. Nobetterdeal's items change daily, and most of their inventory is very limited, but I hope that this helps someone out. Baby stuff is just so expensive. Luckily I've been there done that so I won't be purchasing nearly as much stuff as I thought I needed the first time around.
