Dear Julie G, different shipping methods have different delivery time, you can turn to the link for more information: http://www.banggood.com/Shipping-FAQ_hl86
Thanks.

I ordered something on 11/24/16 and as of today (12/12/2016) the tracking status is still listed as 'Origin Post is Preparing Shipment'. Based on this I would say you have 0.00% chance of ordering something now and having it delivered before Christmas.

You wont get it in time. I paid for express 2-3 business day shipping, it's been 4 business days, and 89 in total, with no expected delivery date.

Shipping is the least of your worries, the quality is bad, and if it's wrong, damaged, or just didn't arrive, they won't help you, or refund you. Shop elsewhere
