I was there for both nights. I was surprised how long the merch line was. I ordered my Metallica shirt off their website weeks in advance and had it in time to be able to wear it during the shows. There was no way I was going to stand in a merch line on the day of a concert. I go to quite a few concerts and no matter who's playing the merch line is always crazy long. You are right it is cheaper to purchase it off their website. BTW you walked passed my section I was sitting in section 422. I had to cut through that line just to be able to get to my section I was sitting in.
