To definitely receive your order by 12/24 via our free FedEx Ground shipping, please place all orders by noon EST on Wednesday 12/14. Orders placed after 12/14 but before 12/20 may still arrive in time but we can't guarantee their arrival.
For reference, we ship our kits from the Midwest and they usually take 1-2 business days for fulfillment. Below are standard regional shipping times for FedEx Ground. Please remember that your order may take extra time to travel during the busy holiday season.
