i think they are slightly cheaper. you still pay a service fee but it's not as bad as a TM or LN fee. also, bzerk must've had a rare occurrence (which i personally would have contested) with the multiple ups fees. sorry to hear about that. i had a few issues with tickets arriving on time and switching them to will call, but everything was always sorted out and i never missed a show. sometimes i spent a good chunk of time arguing with what seemed like the absolute most incompetent person in the world but things were always made right. since that, they've treated me well. i've purchased a very large number of tickets through them since 2010, and i always trust it, and get great seats. i don't know about everybody else but within the past 2 tours or so they've finally started sending me all my tickets at once together in the same envelope.
the only advice to give is know what you want. don't log on there and start deciding picking/choosing. know exactly what you're doing when you log on, get it done, and don't waste any time. every second counts.
who else is gonna bring you, a broken arrow?
