Overstock. They have great prices on things, and their cost for shipping is always $2.95, no matter how much you order! We bought our crib there for $150, regularly like, $250 I believe.
I even bought our king sized comforter set for $17 from their auctions page. If you want to take a risk you can even auction off their returned items, that's how I got our comforter. Unfortunately it wasn't in mint condition, but for $17 we feel fine with that.
I signed up for their OMail and get coupons and notices about sales pretty much daily. One great experience I had with Overstock was...
We shopped around and bought our crib for about $180, which was a great deal. The next weekend was black friday and the crib went down in price about $20. I called Overstock and asked them if I could get the difference in price credited to me since I had JUST bought it...and they did! So now I have a $20 credit going toward my next purchase there.
I have been really impressed with their prices, products, and service, and that's why I'm promoting them. Check it out!
Happy savings to you :)
