Cobby33Joann- I'll send you my last Remedies exam to answer this question of yours 
If you agree via email to buy a card, and the seller tells you he no longer has it or it is not for sale, has there been a breach of contract? What if you see it for sale a month later on the BST, or in the Pick Ups thread because someone else bought it? Can you do anything about it (assume it would be worth it - a higher end card)?
How about- can specific performance be ordered if the seller still has the card?
