There are a few reasons for this:
1. Your package has just been shipped, but the carrier has not yet updated the tracking details.
2. Your package has been picked up by the carrier but has not yet been processed.
*Look for “Your ESR Order” in the inbox of the email you used for this order. The date your order was shipped is included in this email. If the tracking information has not been updated for more than 3 business days after the shipment date or you can’t locate the email, please contact our customer support team.
3. The item you purchased is out of stock in your local warehouse and is being shipped from a warehouse overseas. It has not yet reached your country/state and you will need to switch to an overseas carrier mentioned in your shipping email (please refer to the picture below).
