What does "estimated delivery date" mean?

In the order confirmation email, you will receive an "Estimated Delivery Date". Please note this is not a guaranteed delivery date for your order. Sometimes our system calculates this estimated date without considering the following factors: 

• Order ship within 1-3 business days. 
• The day of the week you are placing the order: All packages are shipped Monday- Friday, unless it is a holiday. 
• The day a parcel ships cannot be counted as an 'in transit' day.

Please use the tracking information to follow the progress of your shipment for a more accurate estimate.
