I tried to buy 5 tickets on line. Because I wanted to use a credit card that I did not use last year to buy tickets, the site would not let me.
Ticket Master should realize that people have more than one credit card. Why can't they just check the number that is submitted?
Also, I had to sign up as if I wanted an account with Ticket Master.
I wanted to buy 5 tickets to a Crunch game, and use a valid credit card. Ticket Master wouldn't allow me to do it.
I think the Crunch should seriously look into this fiasco (buying tickets on line)
