Recon this is a scam or not?

I really like to check into the websites first. I'm not sure if it's a scam or not. I think you should probably give her a few more days, a week at the latest. If not maybe you should go to her address. That would be really funny to see. lol. But anyway, I wonder why she would go to sell tickets that she hasn't recieved yet? Next time if you go to a concert and need tickets I advice you get them off of a big website that a lot of people use. i never heard of gumtree before.
