Postcards under $20 are shipped via eBay Standard Envelope, which is mailed out and delivered by the Post Office. 

Please note that eBay Standard Envelopes are not scanned into the system in the same way that regular packages would be. The tracking can be slightly unreliable. Your item may state that it is "delivered" when it arrives at your local post office. Please be patient, but don't hesitate to reach out to us if your postcard has not made it to you safely.
