You know, it's whatever you feel is right! If you really feel like you want it, then go for it! If you think you're jumping the gun a little too early, then hold off. But it sounds like you want it, so if that's what you want then get it! Sounds like a killer deal!
I think the lady above has a valid point, check the reviews if you can! Just find the same furniture on walmart.com, targt.com, babiesrus.com, or wherever it's cold and you should be able to look at the reviews.
I don't think your crazy at all! Look at the brand/model and see if you can get reviews on it. Otherwise I'd say go for it! If I had a deal like that when I was pregnant the first time I would have gotten it in a heartbeat IF the brand/model were decent and had good reviews.
