Short on purpose. These are the rules people actually have to follow, and a rule nobody reads protects nobody.
1. Ship within 3 business days
Share a delivery address using the address box in your conversation with the other trader, not by typing it into a message. It is deleted after 48 hours, and only that one person can open it. Never post an address in a public place.
Once a trade is confirmed, send your cards within three business days. If something comes up, say so in the trade thread before the deadline, not after.
2. Enter tracking
Where tracking is required for the trade's value tier, enter the tracking number on the trade page when you ship. A trade without tracking is much harder to resolve if a package goes missing.
If you sent it without tracking anyway (a plain letter, for example), you can still mark it sent by confirming on the trade page that the loss is yours if it does not arrive. The other trader sees that you did. A dispute over a parcel sent that way goes against the sender. Where a signature on delivery is required, sending without tracking is not allowed.
3. Pay only with PayPal Goods & Services
If cash is part of the trade, use PayPal Goods & Services.
Never use Friends & Family. Friends & Family has no purchase protection. If you send money that way and the cards never arrive, PayPal cannot help you and neither can we. Anyone who asks you to pay by Friends & Family is asking you to give up your only protection, report them.
4. Describe condition honestly
Describe what you are actually sending. Note creases, whitening, edge wear, surface scratches and print defects. Photograph the real card, not a stock image. "NM" on a card with a soft corner is how disputes start.
5. No counterfeits, no proxies
Do not trade counterfeit, reprinted-as-genuine, or proxy cards. Not as filler, not as a bonus, not knowingly and not carelessly. This one ends accounts.
6. Confirm receipt promptly
When your cards arrive, confirm receipt on the trade page. The other person cannot close out the trade or build a reputation without it, and leaving it hanging is the most common avoidable complaint we see.
7. Report problems, do not retaliate
If a trade goes wrong, report it. Do not retaliate with a false report, a misleading review, or by withholding cards you have already agreed to send. Retaliation is treated as its own violation, separately from whatever started it.
