You can find a lot of the things here cheaper online but it's a great resource to target what items you would like to buy. We did their Baby Registry program which gives back 10% of all registry purchases. We have very generous friends and family so we got a nice chunk back a few months after the baby was born.
They have a very lenient return policy - a few items we brought back - they were all new condition but we didn't have the receipt but since it was on the registry they allowed us to return for exchange or gift card.
