Card buying protocol on the board?

[Leon]

There aren't many rules because rules suck, generally. Act professionally, communicate well and PM me if there is any shadiness. Also, vet your trading partner. If you need to you can PM and I usually have a good idea. Caveat Emptor....and yes, first to say I will take it should get it unless there is an extraordinary reason. Be careful. If someone has 1 post and is selling something too good to be true, it's probably too good to be true.

These were from the BST, and originally from my first collection sale. I was the second owner of these cards, from an original family collections, and the 4th owner.

The general rule is the card is sold to the first person who makes an acceptable offer. I don't know why a seller would continue to advertise and send photos for a card that has been sold. A common problem for sellers is waiting around for querying or requesting potential buyers to make (or never make) offers and return (or never return) messages. Many people sell with a figurative (or, on eBay, real) "Buy it Now" button in the sale's description: First person to press the button, or email "I'll buy it", gets it.

Certainly, a seller can and some may say "Someone else emailed about the card first and I'll give him a little bit to respond," but it isn't a requirement

Though I understand and appreciate the OP's sentiments.
