Shipping Guides & Tracking Tips

Pack trading cards in a penny sleeve, then a top loader, then a bubble mailer, and add tracking — the layers are what stop bends and pressure damage in transit.

A standard domestic stamp will not carry a letter overseas on its own — international mail needs globally accepted postage, and how much depends on the destination and weight.

Yes, a post box accepts an international letter as long as the postage is sufficient; short-paid mail returns to your return address marked insufficient postage.

Close a PO Box online through your USPS account or in person at the Post Office — either route still needs one visit to collect remaining mail and hand back the keys.

Collect on Delivery has USPS take payment from the recipient at delivery and forward it to the sender by check or money order.

Approved Postal Providers are retailers licensed to sell stamps and accept mail, so you can send a letter or a package without going to a Post Office.
