Mine wasn't shipped until Friday afternoon.
Scheduled for a Tuesday arrival.
If it happens again, I am probably jumping off DCBS. I am at the point now where I don't save as much money through them (as I am almost down to the 10 titles I want to be at) so I can almost spend the same amount at the LCS with a regular 10% discount. Yes, I seem petty for being mad at a two day shipping delay, but I kinda worked my schedule around Saturday reading, like I try to do every time I get my monthly haul, and this just throws me behind.
May just use them for my HC/Trade needs if it happens again.
