Comic shortages..

I went to three of our local shops today trying to locate the latest Escalation, only to be told that they were sold out. This has happened on several occasions recently. I think I'm going to just go with online sellers and subscription programs from now on.
Has anyone else had this problem. It just seems to me that, in my case at least, local shops aren't ordering enough product. I don't recall EVER having this problem back in the 80's, or with the DW comics. Is it the comics shops fault, or is it possible that IDW is not doing enough copies?
Although, I've been buying comics for quite awhile, I've never noticed this trend.
