IDW experienced problems with their Memphis warehouse that services a good 50% of their distribution. Being in Little Rock, that naturally means I'm among those who did not get their copy of TMNT #18 this week.
I should get it next week, though, and I'll post a belated review then.
For those of you who are in the same situation as me, but UNLIKE me, own a tablet or something, TMNT #18 is available for digital purchase from IDW.
