Zulily is a grade A site with many diff deals everyday! They don't actually own any inventory so that's why it may take typically 21days for delivery, it my take awhile longer than bigger retailers but you can't touch their prices anywhere. They place one big order after the event ends and then the orders are filled, sent to Zulily, and shipped out. As to quality, everything is different you just have to know how to shop. I've been an avid customer for years and only had one mess up, at that time the customer service I got was outstanding and they definitely made it right for my children:)
Love them and will be referring them for future reference!
