When tracking shows "Pre-Shipment Info Sent to USPS" it means the package is still being held/sorted by USPS. No need to panic! Most likely your package has been sorted by USPS and sent off without being scanned. You will end up receiving your package without any further tracking updates.
If more than 10 business days go by and you haven’t received your package or any updated tracking info, please fill out a support ticket and we will be happy to assist you further.
