Trusted buyers: envelopes up to $100

Anyone can get a stamped envelope on a single raw card up to $20. Between people who know each other, a $5 tracked label on a $40 card can feel like a waste, so sellers can raise that to $100 for buyers they trust. Over $100, cards always ship with a tracked label.

For sellers

• Go to Sell → Trusted buyers. Add buyers by username, or text friends your invite link: whoever opens it and accepts joins your list, even with a brand-new account.
• Already sold to a friend who wasn't on your list? On the order, choose Trust this buyer and offer an envelope. The order switches only if they accept; your ship-by date doesn't change, so ship by label if they don't answer in time.
• Print the tracked envelope from the order before you mark it shipped: envelope orders over $20 need its barcode, so there are at least USPS sorting scans.
• You can remove anyone, or make a new invite link if the old one got passed around. Orders already placed keep how they were agreed to ship.

For buyers

• On a trusted seller's single raw card up to $100, checkout asks how it should ship. A tracked package is the default; the envelope is your choice each time.
• Envelopes get USPS sorting scans but no delivery confirmation, and USPS doesn't insure letters.
• If you chose an envelope and it goes missing, it isn't covered by Slabs & Singles: message the seller. Problems like a card that isn't as described are still covered as usual.

Limits

• One raw card per envelope. Never slabs, boxes or multi-card orders.
• Up to $100 for the order.
• Both sides agree: the seller by trusting the buyer, the buyer by choosing the envelope.

An invite link is only as safe as the people you send it to. It's your list: only add people you'd trust with a card that has no delivery confirmation.
