IMPORTANT SHIPPING INFO: eBay Standard Envelope This single card ships fast and secure via the eBay Standard Envelope program to keep costs low for you! How the tracking works: Tracking is updated by automated USPS sorting machines, not by your mail carrier. A "Delivered" scan means the envelope has reached your local post office/sorting hub, not your physical mailbox. Please allow 1 to 3 additional business days after a "Delivered" scan for your mail carrier to drop it in your mailbox with your regular letter mail. If it still hasn't arrived after a few days, just shoot us a message! Thanks for choosing Siko Vault!
