Just questioning if eBay permits you to market concert tickets on-line? Do you know if you'll find any restrictions depending on what country you are in?

My parents have just known as me and asked if i could "get rid" of their two tickets to some concert as they wont be able to make it due to an additional family event.

Besides asking pals etc, i thought ebay would be an excellent place to market them.

But whats ebay's policy on marketing tickets? Ive heard alot about it around the news but ive forgotten what happened.

and if it matters, the concert is inside of this coming month

Thanks ahead of time for your advice.
