I ordered a Christmas gift for my nephew on Zulily.com. Once it finally arrived, they mysteriously billed my credit card multiple times (in odd amounts) AND charged me for shipping (which is supposedly free when you spend over $20). When I called to find out what the heck was going on, they explained "We don't bill your credit card until the items ship out. The extra charges you are seeing are for "pre-authorizations. These extra charges will disappear after 72 hours". Ok- we will see. Maybe I'm missing something here, but I don't understand why they would be charging odd "pre-auth" amounts to my Visa AFTER I have already paid for the items and AFTER the items were delivered? Will NOT be using them again.
