Did this Sprint mailer need to be this big?

Look how big that thing is. Heavy paper. It came in the mail. How much did it cost to produce and mail that? It's not particularly attractive and the only reason I opened it was to see what the layout was like... I'm on T-mobile and have no intention of canceling my agreement before it's over. I suspect a normal person in my situation would have trashed this in a second.

I think the main thing that got me was that I ripped it when I opened it because the flaps weren't designed right...
