If you got a good deal on the comics and received them in good shape; I wouldn't worry about it. He probably didn't get the price he was expecting and cut corners. This kind of stuff happens to me all the time. I have learned for myself over the years not to sweat the small stuff. If I got a good deal and the shipping is a little high; I just focus on the great deal I received and not so much on the shipping.
