Once we mail a package we have no direct control over it's handling. First class mail is not a guaranteed delivery date service. USPS estimated delivery dates are guidelines only. Unfortunately, we are unable to see any shipping updates other than what you see online. We do not have access to USPS's proprietary system. Please report to us packages that are 14 days or older from the last scan. At that point we are able to file a lost mail report for you with USPS. Refunds are not available on lost/delayed mail but we will happily replace your item.
