Many items are new and still have the tags on.
"What makes it so special is that it is not a garage sale, it's like a store. We check everything," said consigner Hilde Garcia. "It can't have stains, tears, rips. If it's worn out or used, if it's missing pieces, it gets rejected, it can't be on the floor. So you're getting really fantastic quality stuff, in most cases worn once or with a tag on it."
Founder Kristen Nelson hopes it gives parents a chance to shop and save money at the same time. Those who consign can even make a few bucks. Moms can sell the stuff they no longer need and get a great bargain on the stuff they need.
The sale is so popular that this year, it is double the size.
Moms say the event offers one-stop shopping.
"I found the double stroller I wanted at half the price of retail, so I'm ecstatic," said Jennifer Postma.
The sale runs from March 4 to 6 from 9 a.m. to 5 p.m. On Sunday, shoppers get an additional 50 percent off.
