I actually did cancel my order, ten days after placing it. Zulily credited my account within 24 hours, no questions asked. I just went onto 'orders', checked that the items hadn't been despatched, e-mailed 'customer service' with details of items and said that as the stuff hadn't been despatched would it be possible to have a refund. They gave me my money back into my account within 24-hours. You have to check first - once the goods are on their way to their UK despatcher, it may be too late. My items hadn't left the manufacturer; I think that's the criteria.
